Question

After takeoff, a plane flies in a straight line for a distance of 4000 feet in order to gain an altitude of 800 feet. Find the angle of elevation from the ground to the plane.

Need help please, thank you!

Answer 1

The angle of elevation from the ground to the plane is 11.5 degrees

Explanation:

Given -

Horizontal distance from the point of takeoff to which the plane flies in a straight line = 4000 feet

The vertical distance travelled from the ground to the plane is 800 feet

Angle of Elevation

`Sin X= (800)/(4000) \\X = Sin^(-1)(800)/(4000)\\X = 11.5`

The angle of elevation from the ground to the plane is 11.5 degrees
