Question

one angle of a triangle is the sum of its other two angles . The two smaller angles are in the ratio 2:3. What are the angles of the triangle?​

Answer 1

Let x stand for the measure of angle 1. Then. 2x for angle 2 and finally 3 x for angle 3.

So, x + 2x + 3x = 180

and 6x = 180

Therefore, x = 30, 2x = 60 and 3x = 90.
