Find the angle at the base of an isosceles triangle if you know that it is 3 times less than the angle opposite the base.
Knowing that the sum of the angles of a triangle is 180 °, and the angles at the base of an isosceles triangle are equal, we denote the angle at the base as X, compose an equation and solve it.
X + 3X + X = 180;
5X = 180;
X = 180/5;
X = 36 °.
Answer: The angle at the base of an isosceles triangle is 36 °.
