Question 791321: the measure of an exterior angle of a triangle is 120 degrees and the measure of one interior angle of the triangle is 50 degrees.find the number of degrees in the measure of the largest angle of the triangle Answer by solver91311(24713) (Show Source):
An exterior angle of a polygon and the adjacent interior angle are supplementary. From that you can get one of the angles of the triangle. You are given a second one. The sum of the interior angles of a triangle is 180 degrees, so since you know the value of two of the angles, you can calculate the third.
