The angle at the base of an isosceles triangle is 25 degrees. Find the other 2 corners of this triangle.

Given: triangle ABC, angle A = 25, AB = BC (isosceles)
Decision:
since ABC – isosceles, then the angles at the base are equal. We know that the angle is A = 25, therefore A = C = 25.
2) 180 ° is the sum of all the angles in the triangle, we know two, this gives 25 + 25 = 50, it remains to find the third angle. 180-50 = 130 °
Answer: 25 °, 150 °
