Circle exterior angle theorem

WebExample 1: Using the exterior angle theorem, find the value of x from the following figure. Solution: To find: Value of x. Given: Exterior angle of triangle = 160º. Using exterior angle theorem, x + 3x = 160º. 4x = 160º. x = 160º/4 = 40º. Weby = 40°. Therefore, the values of x and y are 140° and 40°, respectively. Example 3. The exterior angle of a triangle is 120°. Find the value of x if the opposite non-adjacent interior angles are (4x + 40) ° and 60°. Solution. Exterior angle = sum of two opposite non-adjacent interior angles. ⇒120° =4x + 40 + 60.
