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.

WebJan 21, 2024 · Case #3 – Outside A Circle. And lastly, the third situation is when two secants, or a secant and a tangent, intersect outside the circle. In this case, there are three possible scenarios, as indicated in the images below. Notice that the exterior angle that is created by the intersection of two secants or tangents is one-half the difference ...
