The two outer angles of the triangle are 95 and 130 degrees, respectively. Find the angles of the triangle.

We will solve this problem by action.

At the first stage, knowing that the sum of the inner and outer angles of the triangle is 180 °, we find the two inner angles of the triangle.

As a result, we get the following angles 180 – 95 = 85 ° and 180 – 130 = 50 °.

By the second action, given that the sum of the three interior angles of the triangle is 180 °, we will find the third angle of the triangle.

As a result, the calculations will have 180 – 85 – 50 = 130 – 85 = 45 °.

Answer: 45 °, 50 ° and 85 °.
