Step-by-step explanation:
Given 2 sides of a triangle then the third side x is in the range
difference of 2 sides < x < sum of 2 sides , that is
19 - 11 < x < 19 + 11
8 < x < 30
Answer:
8 < x < 30
Step-by-step explanation:
The rule for side lengths of a triangle is:
the sum of two side's must be bigger than the third side and their difference must be smaller than the third side :
19 - 11 < x < 19 + 11
8 < x < 30
The sum of two integers is (-32). Their quotient is 7. What are the integers?
===========================================================
Explanation:
Let x and y be the two integers such that |x| > |y|. This is another way of saying that x is further away from 0 compared to y.
Their quotient being 7 means x/y = 7 which rearranges to x = 7y
The sum of the integers is -32 which allows us to say....
x+y = -32
7y+y = -32
8y = -32
y = -32/8
y = -4
Use this y value to find x
x = 7y
x = 7*(-4)
x = -28
The two integers are -28 and -4.

Find the value of x given in the right triangle
Answer: 7.1 units
Step-by-step explanation:
Using Pythagorean theory, c^2 - a^2 = b^2
We know c= 10
We know a=7
We are looking for b
10^2 - 7^2 = b^2
51= b^2
Take square root of both sides
7.1=b
determine the equation of a line that goes through (-1,2) and (7,2)
Answer:
Step-by-step explanation:
To evaluate such, the following must be comprehended:
Slope: Rise/Run.
X-intercept: The peculiar point in which the observed linear data intersects the x-axis.
Y-intercept: The peculiar point in which the observed linear data intersects the y-axis.
To evaluate for the slope, which is defined as the agglomerate distance between two points contained within linear data, the following equation must be utilized:
m = (y2 - y1) / (x2 - x1)
Points utilized or given: (-1, 2) and (7, 2).
2 - 2 / 7 + 1 = 0/8 ==> 0
Henceforth, the slope for the particular configuration, as provided, is understood as zero (0).
Utilizing the integral of one of the points provided, as well as slope evaluated for, the following equation could be exploited:
Point-Slope Formula:
Y- y1 = m(x - x1)
Y - 2 = 0(x - 7)
Y - 2 = 0
Y = 2
Hence, the answer to the peculiar interrogate is disclosed as 2, which is identified as where the horizontal line intersects the y-axis at (0, 2).

If one angle of a triangle is 60°and the ratio of other two is 1:3,find all the angles and the ratio of the sides.
Answer:
30, 90
1 : √3 : 2
Step-by-step explanation:
let the smaller angle be x
hence, the other angle = 3x
180-60=4x
4x = 120
x = 120/4 = 30
other angle = 3(30) = 90
the triangle is a 30-60-90 triangle,
hence the ratio of the sides are 1:√3:2
( short leg : long leg : hypotenuse )
Find the measure of 2
Answer:
92
Step-by-step explanation:
Angle 2 and 92 are corresponding angles and corresponding angles are equal when the lines are parallel
Answer:
[tex]\angle 2=92^{\circ}[/tex]
Step-by-step explanation:
When two parallel lines are cut by a traversal, their corresponding angles are always equal. Corresponding angles can be found if you took each point of intersection and aligned them up with each other.
In this case, we see that [tex]\angle 2[/tex] and the angle marked as 92 degrees correspond with each other. Since all corresponding angles are equal, we have:
[tex]\angle 2=\boxed{92^{\circ}}[/tex]

The simple interest formula is I = Prt, where I represents simple interest on an amount, P, for t years at a rate of r, where r is expressed as a decimal.
What is the amount of money, P, that will generate $40 in interest at a 10% interest rate over 5 years?
$60
$80
$90
$100
Answer:
80
Step-by-step explanation:
I = Prt
I = 40 R = .10 T = 5
40 = P (.10)(5)
40 = P(.5)
Divide each side by .5
40/.5 = .5P/.5
80 = P
The interest over 5 years is $80.
The correct option is B.
What is the simple interest?Simple interest is the borrowing amount added only to the principal amount.
The Formula to calculate the simple interest is;
S.I. = P x T x R / 100,
Where S.I. is simple interest, P is the principal amount, T is the time period and R is the interest rate in a year.
We can use the formula I = Prt to solve for P. We know that I = 40, r = 0.10, and t = 5. Substituting these values, we get:
40 = P(0.10)(5)
Simplifying:
40 = 0.5P
Dividing both sides by 0.5:
P = 80
Therefore, the amount of money, P, that will generate $40 in interest at a 10% interest rate over 5 years is $80.

Chang has 2 shirts: a white one and a black one. He also has 2 pairs of pants, one blue and one tan. What is the probability, if Chang gets dressed in the dark, that he winds up wearing the white shirt and tan pants? Show your work.
Answer:
The probability that Chang gets dressed with a white shirt and tan pants is 25%.
Step-by-step explanation:
Given that Chang has 2 shirts, a white one and a black one, and he also has 2 pairs of pants, one blue and one tan, to determine what is the probability, if Chang gets dressed in the dark, that he winds up wearing the white shirt and tan pants the following calculation must be performed:
Each shirt = 50% chance
Each pants = 50% chance
0.50 x 0.50 = X
0.25 = X
Therefore, the probability that Chang gets dressed with a white shirt and tan pants is 25%.

Determine whether side-angle-angle (SAA) is valid means for establishing triangle congruence. In this case, you know the measure of : side, an
adjacent angle, and the angle opposite to the side. If it is valld criterion, explain why. If it is not valid, use GeoGebra to create a counterexample
demonstrating that it doesn't work and give an explanation. If you construct a counterexample, take a screenshot of your work, save it, and insert
the image in the space below.
Answer:
Basically if you know side-angle-anlge, you can determine the third angle by
3rd angle = 180 - angle 1 - angle2
In this way, you are using the Angle-Side-Angle method of congruence.
Step-by-step explanation:
Answer:
In this case SAA is a valid means for establishing triangle congruence. You can see in the following image. The triangles are the same, in other words congruent. How I figured it out was by making a random triangle (ABC) then finding the lengths and angles. From there, I picked a random side (AB) and angles (A) and (B) after I transferred the information I had and put it into a new triangle. Using this formula to determine the third angle: 3rd angle (C = 45*) = 180* - angle A (45*) - angle B (90*). From there, I looked for where line (BC) and (CA) would connect. Leaving me with two congruent triangles.

Use the given conditions to write an equations for the line in slope- intercept form. passing through (1,-8) and (-7,8)
Answer:
y = -2x - 6
Step-by-step explanation:
Going from the first point to the second, we see x decreasing by 8 from 1 to -7 (this is the 'run') and y increasing by 16 from -8 to +8 (this is the 'rise'). Thus, the slope of the line through these two points is m = rise/run = 16/(-8) = -2.
Using the point-slope formula y - k = m(x - h) and the point (1, -8), we get:
y + 8 = -2(x - 1), or
y = -8 - 2x + 2, or
y = -2x - 6 (in slope-intercept form)

These pictures are the questions given in the pdf, let's get the solutions.
1) Solution
It is given that,
→ <5 = <6
Then the co interior angles,
→ <5 + <4 = 180°
Now substituting value of <5,
→ <6 + <4 = 180°
This shows property of co interior angle.
Therefore, L ll m
2) Solution
Take it as,
→ <1 = 90°
In above eq. L is perpendicular to t.
→ <2 = 90
In above eq. m is perpendicular to t.
Then it will be,
→ <1 = <2
It shows property of corresponding angle.
Therefore, L ll m.
3) Solution
It is given that,
→ <1 = <2 and <1 = <3
Now substitute,
The value of <1 in second one,
→ <2 = <3
This shows property of alternate angle.
Therefore, ST || UV.
4) Solution
It is given that,
→ <RSP = <PQR --- (1)
→ <QRS + <PQR = 180° --- (2)
Now from the equation (1) and (2),
→ <RSP + <QRS = 180
It shows property of co interior angle.
Therefore, PS || QR.

find the perimeter of the figure
Answer:
72cm
Step-by-step explanation:
We have 4/6 sides. 4 of them are given, and they are 13.25cm, 7.25cm, 7.75cm, and 22.75cm.
The perimeter is found when you add all the lengths of the sides of a figure.
So far, we can add 13.25+7.25+7.75+22.75 = 51cm.
Let's call the first ungiven side A. We can see that 7.75cm + A = 13.25cm. Using this, we can figure out that A = 13.25-7.75 = 5.5cm.
We can call the second ungiven side B. We see that 7.25cm + B = 22.75cm. So, B = 22.75-7.25 = 15.5cm.
Now, let's add everything together. 51cm + A + B = Perimeter. 51cm + 5.5cm + 15.5cm = 72cm.
Hope this helps! Feel free to ask any questions if this doesn't make sense. :)
