A radio tower is anchored by long cables called guy wires, such as AB in the figure shown below. Point a is 250m from the base of the tower, and m (degrees). Part a) how long is guy wire AB? round to the nearest tenth.
Part b) how far above the ground is AB fastened to the tower?
Part c) how tall is the tower, DC, if m(degrees)? Round to the nearest tenth.

a triangular prism is a 3 dimensional shape composed of triangles and rectangles. it is made from two triangular bases and three rectangular sides.  

i will with my problems and all the other things that need to   be on by the way

step-by-step explanation:

  or  

sin y = 7/q

7 is the opposite side length, q is the hypotenuse

tan y = 7/r

7 is the opposite side length, r is the adjacent side length

using sohcahtoa ^^^^

cos y = adjacent/hypotenuse

cos y = r/q
