Question

A plane rises from takeoff and flies at an angle of 90° with the horizontal runway when it has gained 400 feet find the distance that the plane has flown.

Answer 1

2879ft

Explanation:

The level runway (x), height gained (h), and distance travelled (r) form a right-angled triangle with base angle

.

We may hence use trig ratios to solve for any of the unknowns, in particular for the distance r as follows :
