Question

A plane rises from take-off and

flies at an angle of 20° with
the horizontal runway. When it
has gained 750 feet, find the
distance that the plane has
flown.
A
C =
ft
(Round the answer to the nearest whole number.)
C = ?
20°
B
750 ft
C

Answer 1

2193 ft

Explanation:

You're basically solving for the hypotenuse (h) of a right triangle with a base angle of 20° and an opposite leg of 750 ft.

sin20 = 750/h

h = 750/sin20 ≈ 2193 ft
