Angles are measured using degrees, ranging from 0 all the way to 360 degrees in one full turn. There are many different types of angles, but possibly the most easily recognisable is the right angle.

With two angles and one side of a triangle, trigonometry reveals the lengths of the other sides, and thereby, the height of the triangle (the mountain).
