Question

2.The ratio of interior angles of a triangle is 3:2 and their opposite exterior

angle is 1650

.What is the measure of each interior angle?

​

Answer 1

Step-by-step explanation:

let the first interior angle be 3x

second interior angle be 2x

exterior angle = sum of two interior angles

150 = 3x+2x

3x + 2x = 150

5x = 150

x = 150/ 5

x = 30

hence the first interior = 3x = 3 × 30 = 90°

second interior angle = 2x = 2 × 30 = 60°
