WebStep 2: Use what we learned from Case A to establish two equations. In our new diagram, the diameter splits the circle into two halves. Each half has an inscribed angle with a ray on the diameter. This is the same situation as Case A, so we know that. (1)\quad\purpleC {\theta_1}=2\blueD {\psi_1} (1) θ1 = 2ψ1. and. WebMar 15, 2024 · Example 5.2.1: Evaluating a Trigonometric Function of a Right Triangle. Given the triangle shown in Figure 5.2.3, find the value of cosα. Figure 5.2.3. Solution. The side adjacent to the angle is 15, and the hypotenuse of the triangle is 17, so via Equation 5.2.4: cos(α) = adjacent hypotenuse = 15 17. Exercise 5.2.1.
