One of the outer corners of an isosceles triangle is 130 degrees. find the degree measure of the larger of the inner angles of this triangle.
By definition, the magnitude of adjacent angles is 180 degrees, and a triangle. by condition is isosceles, therefore in a triangle there are 2 angles of 50 degrees each. 180 – 130 = 50.
Based on the fact that the sum of the interior angles of the triangle is also 180 degrees, we find the third angle: 180 – 50 – 50 = 80 degrees.
Answer: The larger angle of the triangle is 80 degrees.
