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. http://cdn.kutasoftware.com/Worksheets/Geo/6-Polygons%20and%20Angles.pdf
