Question

Guy wires 80 feet of support for a 65- foot tall telephone Pole. To the nearest degree, what angle will the wires make with the ground? round to the nearest tenth if necessary

Answer 1

54.3deg

Explanation:

sin(angle) = 65/80

angle = 54.34deg

Answer 2

The answer is 54.3deg.

Explanation:

The telephone pole, guide wire and the ground form a right-angled triangle.

Sine function of the angle between wire and ground = opposite side / hypothesis

= Pole height / Guide wire length

= 65 / 80

= 0.8125

The angle between wire and ground = inverse sine(0.8125) = 54.3deg.
