Question

Each of the two equal angles of a triangle is 5/8of the third angle. Find the angles of the triangle.​

Answer 1

If the third angle is x, the other two angles are 2x

The measure of the angles of a triangle must add up to 180 degrees

x + 2(2x) = 180

x + 4x = 180

5x = 180

x = 36

The other two angles are 2x = 2 * 36 = 72

The three angles are 36, 72, and 72 degrees.
