The largest Egyptian pyramid is 146.5 m high. When Nika stands far away from the pyramid, her line of sight to the top of the pyramid forms an angle of elevation of 20 degrees with the ground. What is the horizontal distance between the center of the pyramid and Nika? Round to the nearest meter.

First, you need to figure out whether you need to use sin, cosine or tan.
Since we know that we need to find the adjacent side of the triangle and also since we already know the opposite side of the triangle from the angle, we can use tan.
tan(20)=opposite/adjacent
tan(20)=(146.5)/adjacent
adjacent=(146.5)/tan(20)

403 meters away form the pyramid
