Answer: 
≈3.46
Step-by-step explanation:
1. Based on the information given in the problem you can draw the triangles shown in the figures attached, which are not drawn to scale ("x" represents the lenght of the hyteponuse in the first triangle, which is equal to the lenght of a leg in the second triangle).
2. Calculate x using the first triangle:
3. Now, you can calculate y as following:
≈3.46
[tex]4r^{2} =64
r^{2} =16
r= \sqrt{16} = ±4
t is vertical to s because they share a point and are directly across from each other. vertical angles are congruent. therefore s=113 degrees
t and p are corresponding angles, which means they are congruent. this means p is also 113 degrees.
s and o are corresponding angles, so o is also 113 degrees.
t and u are supplementary. they share a straight line, so they add up to 180. you can find u by subtracting 113 from 180. 180-113= 67, so u is 67 degrees.
u and r are vertical angles, so r is 67 degrees.
r and m are corresponding, as well as u and q. therefore m and q both equal 67 degrees.
