Question:

Dash sees a rocket at an angle of e!evation of 11 degrees If Dash is located 5 miles from the rockets launchpad, how high is the rocket?

Answers

  about 5130 feet high

Step-by-step explanation:

The tangent ratio is defined as ...

  Tan = Opposite/Adjacent

Here, that means ...

  tan(11°) = (rocket height)/(distance to launchpad)

  rocket height = (5 mi)tan(11°)

   ≈ (5 mi)(0.19438) ≈ 0.9719 miles ≈ 5,132 feet

The rocket is about 5132 feet high.

For this, we have to assume a flat earth with no atmosphere. If Dash is standing on the ground on a round earth, the horizon is about 3 miles away, so the launchpad is over the horizon.

__

Of course, you know there are 5280 feet in a mile.
