Question

If one angle of a triangle is 60° and the other two angles are in the ratio 1: 2, find the angles.

Answer 1

Given, one angle of a triangle is 60°.

Let the other two angles be x and 2x.

We know that, the sum of all angles in a triangle is equal to 180°

x + 2x + 60° = 180°

3x = 180° - 60°

3x = 120°

x = 40°

So, the other two angles will be x = 40° and 2x = 2 x 40° = 80°.
