Question

the ratio of interior angles of triangle is 3:2 and their opposite exterior angle is 150. what is the measure of each interior angle​

Answer 1

Step-by-step explanation:

let first interior angle be 3x

and second interior angle 2x

exterior angle = sum of two interior angles

150 = 3x +2x

150 = 5x

150/5 = x

30 = x

First interior angle = 3x

3(30)

=90°

second interior angle = 2x

= 2(30)

60°
