Answer:
= x
Step-by-step explanation:
Basically, find the missing side lengths of each triangle so that you can solve for x:
1. right triangle w/ side lengths 48 and 52
- 48^2 + (missing side)^2 = 52^2
- 2304 + (missing side)^2 = 2704
- (missing side)^2 = 400
- (missing side) = 20 (use this for next triangle)
2. right triangle w/ side lengths 12 and 20 (from previous triangle)
- 12^2 + (missing side)^2 = 20^2
- 144 + (missing side)^2 = 400
- (missing side)^2 = 256
- (missing side) = 16 (will be used with next triangle's missing side)
3. right triangle w/ side lengths 5 and 13
- 5^2 + (missing side)^2 = 13^2
- 25 + (missing side)^2 = 169
- (missing side)^2 =144
- (missing side) = 12
Take right triangle w/ side lengths 12, 20, and 16 (#2) and right triangle w/ side lengths 5, 13, and 12 (#3):
- the value of 12 (missing side of #3) subtracted from the #2's missing side, 16, (not its hypotenuse that equals 20 which was found from #1) will equal <u>the missing side length that will be used to find 'x'</u>
- 16 - 12 = 4 ---> so the side lengths are 4, 5, and x
4. Solve for the final triangle that includes x:
- 4^2 + 5^2 = x^2
- 16 + 25 = x^2
- 41 = x^2
- = x

What is Vertex Angle?</h3>
Vertex angle is defined as the angle formed by two lines or rays that intersect at a point. These two rays make the sides of the angle.
Here, Vertex is the point which is located over the center of the base of a regular pyramid.

Answer:
1)An angle bisector is basically the division of an angle into two equal parts, so you should just draw a line in the middle after you found the angles using the compass
2) parallel lines is a pair of lines that never intersect, and are always the same distance apart. you should use the compass to draw a 90-degree angle at the end of the line XY, and use the straightedge to draw a line that is parallel to the line XY.
