Question

A plane took off from the runway. When the plane had flown 1000 m, it had covered a horizontal distance

of 800 m. Find the measure of the angle to the nearest degree at which the plane rose from the ground.
1000

Answer 1

36.9 degrees

Explanation:

distance that the plane travels (hypotenuse) = 1000m

horizontal distance (adjacent) = 800m

cos(angle) = adjacent/hypotenuse

cos(angle) = 800/1000

angle = cos-1(800/1000)

angle = 36.9 degrees
