Question

Nick is stuck at the top of a Ferris wheel his mother is standing 38 feet from the base of the wheel watching him if the angle of elevation from Nick‘s mom to neck is 73° how far off the ground is Nick

Answer 1

124.3 feet.

We are looking for the side opposite the angle we know.  We have the side adjacent to this angle; opposite/adjacent = tangent:

tan 73 = x/28

Multiply both sides by 28:
28 tan 73 = x
124.3 = x
