Question

An airplane took off and flew at an angle of elevation 12° with the ground. What was the approximate altitude of the airplane, (high how is the plane directly from the ground), after it had flown 8,000 meters (hypotenuse)?

Answer 1

1663 m approx.

Explanation:

We have a right triangle in which we know the hypotenuse and need to find the opposite side, so we use the sine function:

sin 12 = h / 8000

h = 8000 sin 12

= 1663 m approx.
