Two lines are intersecting. What is the value of x? Enter your answer in the box. (x + 23) (2x + 4)° Help! Please!!!
Answer:
[tex]x = 51^o[/tex]
Step-by-step explanation:
Given
Intersecting lines

Find x
To do this, we make use of:
[tex]x + 23^o + 2x + 4^o = 180^o[/tex] --- angle on a straight line
Collect like terms
[tex]x + 2x = 180^o - 4^o - 23^o[/tex]
[tex]3x = 153^o[/tex]

[tex]x = 51^o[/tex]

Which of the following accurately compares 15 - v105 and 5?
PLEASE HELP ME
Answer:
[tex]\sqrt{105}[/tex] is slightly more than 10, so 15 - [tex]\sqrt{105}[/tex] is less than 5.
Step-by-step explanation:
Given expression is (15 - √105).
Since, √105 ≈ Slightly greater than 10 [Since, [tex]\sqrt{100}=10[/tex]]
Therefore, when we subtract the value of [tex]\sqrt{105}[/tex] from 15,
15 - [tex]\sqrt{105}[/tex] = Slightly less than 5
From the given options answer will be,
[tex]\sqrt{105}[/tex] is slightly more than 10, so 15 - [tex]\sqrt{105}[/tex] is less than 5.

If the supplement of an angle is 4 times of its compliment, find the angle.
PLSSSSSSSSSSS HELP ASAP
Answer:
The angle is 60°
Step-by-step explanation:
A supplement angle is the angle whose sum is equal to 180°.
The supplement angle = 180° - x
A complement angle is the angle whose sum is equal to 90°.
The complement angle = 90° - x
Given,
supplement angle = 4 × complement angle
(180° - x) = 4 × (90° - x)
180° - x = 360° - 4x
4x - x = 360° - 180°
3x = 180°
x = 60°
The supplement angle = 180° - x
⇒ 180° - 60°
⇒ 120°
The complement angle = 90° - x
⇒ 90° - 60°
⇒ 30°
Answer:
The angle is 60 degrees.
Step-by-step explanation:
Let the angle be x.
Then its supplement = 180-x.
Its complement = 90-x, so we have the equation:
180 - x = 4(90 - x)
180 - x = 360 - 4x
-x + 4x = 360 - 180
3x = 180
x= 60 degrees.

G
35 m
Find the value of x:
H
18 m
30 m
Answer:
21 is the answer
Step-by-step explanation:
from the figure it can be seen that
angle G = angle J
angle H = angle K and
angle I = angle L
thus triangle GHI is similar to triangle JKL and in 2 similar triangles the ratio of their corresponding sides is same. that means
[tex] \frac{hi}{kl} = \frac{gi}{jl} \\ \frac{18}{30} = \frac{x}{35} \\ x = \frac{18}{30} \times 35 \\ x = \frac{3}{5} \times 35 \\ x = 3 \times 7 \\ x = 21[/tex]

What is the length of leg s in the right triangle shown?
Answer:
D. 5
Step-by-step explanation:
Applying,
cos∅ = adjacent/Hypotenuse
From the diagram,
Given: ∅ = 45°, adjacent = s, hyptenuse = 5√2
Therefore,
cos45° = s/5√2
make s the subject of the equation
s = cos45°×5√2
s = (1/√2)(5√2)
s = 5
Hence the right answer is D. 5

Can I get help with these questions 17,18,20,22,23,27,30 &31
Only reply if you are seriously going to help me please
No spam I would really appreciate it
Answer:
17) just take the root of 100. the text says its square(d).
10m
And checking it gives 10m * 10m = 100m²
18) you need to learn some square numbers to ace this topic. it isn't that complicated, just multiply natural numbers with themselves
like
1² = 1
2² = 4
3² = 9
4² = 16
5² = 25
6² = 36
7² = 49
8² = 64
Now we can see that a) sqrt(55) lies between 7 and 8, and that its value is somewhere in between
7 < a < 8
(ignoring the negative solution to the root oc)
try b, c and d yourself. if you struggle, leave a comment.
I got a problem finding exercises 19 to 21, seriously....
22) well...
a * b = 18ft²
6ft * 3ft seems just right. pure guesswork here, seems to be to easy with these numbers.
but we can also write it as a system of two functions
a * b = 18ft²
a = 2b
and then solve it by substituting a in line one with 2b, since a is 2b this is allowed.
2b * b = 18
2 b² = 18
b² = 9
b = 3
(we ignore -3 as a solution bc negative length makes no sense)
plugging that b into line two of the system gives
a = 2 * 3
a = 6
27) rationale can we written as a ratio (a fration)
it almost sounds too simply
rationals are either the root of square numbers, bc they can be solved cleanly, or they got a repeating pattern after the point.
b and c apply to these rules, a and d not
30) lol, I just figured out where the missing exercises are hidden XD
31) just add up the three rectangles (easy part) with the two triangles top and bottom each triangle is just 12m * 16m / 2 (bc it's a triangle, not a rectangle). since you got two triangles you just multiply by two (it's like ignoring the decision. also, the two triangles together would indeed make just a n9ce rectangle).
if you really need the values, leave a comment, but that will not help you in any test.
you can also post your solutions and I'll check them.
32) area of the circle times two
plus area of a rectangle wrapped around the cylinder.
circle are is pi*r² -> pi * (28 in)²
(remember to double for two circles)
rectangle is the circumference of the circle (pi * 28in) times the height of the cylinder
like in 31), feel free two post your results or ask for values if you really struggle to grasp the pattern here.
hope you have a great day and that you understand some more of the topic. you can ace it :)
