Question

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

Answer 1

Answer:

let the first interior angle be 3x

second interior angle be 2x

exterior angle=sum of the two interior angles

150=3x+2x

3x+2x=150

5x=150

x=150/5

x=30

hence,

first interior angle=3x=3*30=90°

second interior angle=2x=2*30=60°
