Question

In ΔNOP, the measure of ∠P=90°, NO = 83 feet, and OP = 49 feet. Find the measure of ∠O to the nearest tenth of a degree.

Answer 1

When in doubt, draw it out.

What property of the triangles can you determine from the fact that <P is 90 degrees? What do know about triangles that possess this property?

My last hint is that trigonometry of some kind will be useful here, and to remember SOH CAH TOA.

In case it's ambiguous, you will need a calculator to determine the answer to this problem.
