Question
One of the cables that helps stabilize a phone tower is 90 feet long and is anchored into the ground 16 feet from the base of the tower. What is measure of the angle that the cable makes with the ground?
Given:
h = 90 ft
a = 16 ft
Formula:
cos θ = a / h
θ = cos -1 (a / h)
Solution:
θ = cos -1 (16 / 90)
θ = 79.75965168 = 96.76
Final Answer:
C. 79.76°
