Question 2:
The answer is 21
The two angles are vertically opposite, which makes them equal and also means we can make an equation:
4x - 4 = 3x + 17
- 3x
x - 4 = 14
+ 4
x = 21
Question 3:
The answer is 23
Again, the angles are vertically opposite, so we can make them equal each other:
5x - 53 = 3x - 7
- 3x
2x - 53 = -7
+ 53
2x = 46
÷ 2
x = 23
I hope this helps!

Step-by-step explanation:
$23.25 ÷ 0.75 = 31.00
Answer:
0
Step-by-step explanation:
Volume of cylinder = pi r^2 h
diameter = S so the radius = 0.5S and the height of cylinder = S
so Volume of this cylinder = pi (0.5S)^2 * S
= 0.25 pi S^3
Both chords are congruent(equal) so:
5x= 20
divide both sides by 5, and x=4
