A helicopter is hovering above a road at an altitude of 24 m. At a certain time, the distance
between the helicopter and a car on the road is 45 m. calculate the angle of depression from
the helicopter from the car. [

Respuesta :

Answer: 32.23°

Suppose the setpoint of a helicopter is A and that of a car is C and that of the road is B

The distance from the helicopter to the car and the road forms a right triangle

=> ΔABC is a right triangle at B

=> the angle of depression from  the helicopter from the car is ∠ACB

we have: ΔABC is a right triangle => sin ∠ACB = 24/45

=> m∠ACB = 32.23°
