A radio transmission tower is 170 feet tall. How long should a guy wire be if it is to be attached 7 feet from the top and is to make an angle of 30° with the ground? Give your answer to the nearest tenth of a foot

Draw a rt triangle:
X = Hor. side.
Y = 7 Ft = Ver. side.
Z = Hyp. = Length of guy wire.
A = 30 Deg.
Z = Y/sinA = 7 / sin30 = 14 Ft.
y
