Question

The ratio of interior angles of a triangle is 3:2 and their opposite exterior angle is 150 . What is the measure of each interior angles.

Answer 1

Answer:

90° and 60°

Step-by-step explanation:

3:2 = 3x and 2x

Now,

150 = 3x + 2x. [exterior angle property]

150 = 5x

150÷5 = x

30 = x

So,

3x = 3×30 = 90°

2x = 2×30 = 60°
