Question

Holly is looking up at an angle at a helicopter. The direct distance from Holly to

the helicopter is 16 km. The helicopter is hovering 11 km above the ground.
Calculate the angle of elevation from Holly to the helicopter. Include a labelled
diagram in your solution

Answer 1

43.43 degrees

Explanation:

This is a right triangle with the opposite LEG = 11 km and the hypotenuse = 16 km

sin (angle) = opposite/hypotenuse

= 11/16

arc sin (11/16) = angle = 43.43 degrees
