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 angle?​

Answer 1

Answer:

let the angles be 3x and 2x

some of opposite interior angle =opposite exterior angle

3x +2x =150

5x=150

x=150/5

x=30

3x=3×30

=90

2x=2×30

=60
