Answer:
111 =x
Step-by-step explanation:
The exterior angle is equal to the sum of the opposite interior angles
29+82 = x
111 =x
Answer:
Step-by-step explanation:
Since all the angles in a triangle add up to 180, you would need to add up the 2 values you have to get the third:
∠3 = 180-82-29
= 69 degrees
Now you have to subtract this value from 180 because a straight line is 180 degrees:
∠x = 180-69
∠x = 111°
Hope this helps!

Answer:
the anser is no.b that is 30°
Answer:
90°
Step-by-step explanation:
There's are supplementary angles at point C. These are two angles that add up to 180°. We know this because a straight line makes 180° on both sides. Since we know that the first angle is 150°, we can determine the angle a point C is 30°. This is shown by:
180-150=30
So now we know 1 angle and the other two angles are put into like terms (in this case, multiples of x). It is known that the sum of all angles in a triangle equates to 180°. Using this information we can set up a simple equation.
[tex]3x+2x+30=180[/tex]
Combining like terms, we get:
[tex]5x+30=180[/tex]
Isolating x, we get:
[tex]5x=150[/tex]
Dividing both sides by 5, we get:
[tex]x=30[/tex]
So now we can use this x-value to determine the angle that is being asked. It is shown that angle ABC is equal to 3x. Using the x value we just calculated, we get a final answer of:
[tex]3x=3(30)=90[/tex]
Therefore, the answer is 90°. Hope this helps!
In an ecological study, the sampling mean proportion is 0.28 and the sample size is 50. What is the margin of error with a confidence level of 95%?
The margin of error is 0.1245 (approx) with a confidence level of 95%.
What is margin of error ?Margin of error is a statistic which is expressing the measurement of random sampling error in the results of a survey.
Margin of error = [tex]z^{*}[/tex][tex]\sqrt{\frac{p(1-p)}{n} }[/tex]
where [tex]z^{*}[/tex] is the value for confidence level or quantile,
p is the sampling mean proportion and n is the sample size.
How to find margin of error in given problem ?Here, The sampling mean proportion(p)= 0.28
The sample size(n)= 50
Confidence level = 95%
Hence Value for 95% confidence level ([tex]z^{*}[/tex])= 1.96
∴ Margin of error = [tex]1.96[/tex][tex]\sqrt{\frac{0.28(1-0.28)}{50} }[/tex]
= [tex]1.96[/tex][tex]\sqrt{\frac{0.28*0.72}{50} }[/tex]
= [tex]1.96\sqrt{\frac{0.2016}{50} }[/tex]
= [tex]1.96\sqrt{0.004032}[/tex]
= [tex]1.96[/tex]×[tex]0.0635[/tex]
= [tex]0.1245[/tex] (approx)
So, The margin of error is 0.1245 (approx).

As x reaches negative infinity y reaches negative infinity
Step-by-step explanation:
So, first off, when looking at graphs, there will always be a infinite end behavior.
This is because either the x or y axis can be set to a infinitly large number.
We can instantly set up a 2 things for this graph.
We see that y NEVER reaches postive infinity. This is because both left and right sides of the graph have downwards slopes.
This removes our second answer, because it is postive infinity for y.
It also removes our first answer, since it is just 5 for y, notn negative infinity.
Finally, it removes our third answer, since it is just 7 for y, not negative infinity.
This leaves D.
D is correct since y reaches negative infinity when x reaches both postive and negative infinity.
D says x is negativly infinite, which fits this.
So D is our answer.

What is the diameter of a hemisphere with a volume of 896\text{ m}^3,896 m
3
, to the nearest tenth of a meter?
diameter=15m
Answer:
Solution given:
diameter [d]=?
Volume of hemisphere=2/3*πr³
896m³=2/3*πr³
r³=896*3/2π
r=[tex]\sqrt[3]{427.8}=7.5[/tex]
diameter=2r=2*7.5=15m
Radius (r) = ?
Diameter (d) = ?
Volume of hemisphere = 2/3 × πr³
→ 896m³ = 2/3 × πr³
→ r³ = 896 × 3/2π
→ r = ³√427.8
→ r = 7.5
Now,
Diameter (d) = 2r
→ 2 × 7.5
→ 15m is the required answer.

Answer:
1. 24 in
2. 30 in.
3. 14/3/13 in
4. 7 in
5. 5in
Step-by-step explanation:
The scale of drawing to the scale of actual model:
1:6
so when the questions ask for actual, we need to x6.
1. actual width of painting = width of drawing x 6
4in x 6 = 24in
2. actual height of painting = height of drawing x 6
5in x 6 = 30in
3. This one you should take 5/6 and x2 since we have two edges so like
5 - 2(5/6) = 3/1/3
4 - 2(5/6) = 2/1/3
so the final equation should be:
3/1/3 + 2/1/3 x 6 (since we are looking for the actual height of H) = 14/3/13 in
4. actual width of H through center = 1inch + 2(1/2)in (because we have 2 vertical parallel) x 6 so:
2(1/2) + 1in x 6 = 7in
5. Look back on Q3,
drawing top edge to top edge of H = drawing left edge to left edge to H = 5/6
so, 5/6 x 6 = 5in

Answer:
2/3 ft
Step-by-step explanation:
area of triangle =base*height/2
2/5=base*6/5/2
2/5 *2 =base * 6/5
4/5 =base*6/5
4/5÷6/5=base
4/5 * 5/6=base
20/30=base
2/3=base
therefore base=2/3 ft
What is the length of the hypotenuse of the right triangle in the diagram?
Answer:
it's hypotenuse will be -8
Given the triangle below, what is the measure of x to the nearest foot?
Answer:
18 ft
Step-by-step explanation:
Since the triangle is right angled ; we could use trigonometry ;
Using the angle , 40° ; adjacent side, = 14 feets ; hypotenus = x
Cos θ = Adjacent / hypotenus
Cos 40 = 14 / x
0.7660444 = 14 / x
0.7660444x = 14
x = 14 / 0.7660444
x = 18.27
= 18 ( nearest foot)
Solve 2x + 5y = -13
3x - 4y = -8

The equation of a circle is x2 + y2 + 2x - 10y - 38 = 0. What are the coordinates of the
center and the length of the radius of the circle?
Answer:
Centre = (-1, 5)
radius = 8units
Explanation
The standard form of the equation of a circle is expressed as
x^2+y^2+2gx+2fy+C = 0
Center = (-g, -f)
radius = √g²+f²-C
Given the equation of a circle is x² + y²+ 2x - 10y - 38 = 0.
On comparing
2gx = 2x
2g = 2
g = 2/2
g = 1
2fy = -10y
2f =-10
f =-5
Centre = (-1, -(-5)) = (-1, 5)
radius = √1²+5²-(-38)
radius = √1+25+38
radius = √64
radius = 8units

In △XYZ, m∠X = 27° and m∠Y = 48°. Which gives the sides of the triangle in order from shortest to longest?
Answer:
YZ , XZ , XY
Step-by-step explanation:
first lets find angle Z
angle x + angle y + angle z=180 degree (being sum of interior angles of a triangle)
27 + 48 + angle z=180
75 + angle z=180
angle z =180-75
angle z =105 degree
side YZ is the shortest one because the side opposite to the smallest angles is shortest in side.Then ,XZ is shortest in side because the side opposite to the smallest angle is shortest in side.Since angle z is largest angle so the side opposite to angle z will be the longest side i.e XY
first YZ then XZ and XY.
