Question

9 A communications company is building a 30-foot antenna to carry cell phone transmissions. As shown in the diagram below, a 50-foot wire from the top of the antenna to the ground is used to stabilize the antenna. Wire 50 ft Antenna 30 ft Ground Find, to the nearest degree, the measure of the angle that the wire makes with the ground.

Answer 1

sin ( x) = opposite side / hypotenuse

sin (x) = 30 / 50

x = sin^-1 (3/5)

x= 36. 87
