Section 7.1 – Solving Right Triangles 1 Section 7.1 Solving Right Triangles In this section we’ll solve right triangles, which means that you will find either lengths and/or angle measures that are not given. You’ll use any one of the six trigonometric functions of an angle to do this. Example 1: In triangle ABC with right angle at angle C, 30 o m B and AB measures 11 units. Use the given angle and the given side to find the length of BC. An angle of elevation is an angle that is formed by a horizontal ray and another ray above the horizontal. An angle of depression is an angle that is formed by a horizontal ray and another ray
