Question

A helicopter flies 665 feet above ground. What is the measure of the angle of depression from the helicopter to the girl’s line of sight? Round to the nearest degree. 23° 25° 65° 67°

Answer 1

67 degrees

Explanation:

Answer 2

67°

Explanation:

Given:

Height of helicopter from the ground, x = 665 feet

Distance from the helicopter to the girl's line of sight(opposite) = 665ft - 5 ft = 600 ft

Horizontal distance(adjacent) = 280 ft

To find the angle of depression, use the formula:

`tan y = (x)/(y)`

Solve for y:

`y = tan^-^1 ((x)/(y))`

`y = tan^-^1 ((660)/(280)) = 67.01`

Angle of depression = 67°
