Question

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

Answer 1

Step-by-step explanation:

3x+2x = 150

5x=150

=x=150/5=30

3x=3*30=90

2x=2*30=60

Answer 2

Answer:

1. Let the first interior angle be 3×
2. Second angle be 2×
3. Sum of two interior angles = opposite exterior angle
4. 3× + 2× = 150°
5. 5× = 150°
6. × = 150°\5
7. × = 30°
8. Hence,
9. First interior angle = 3× = 3 × 30° = 90°
10. Second interior angle = 2× = 2 × 30 ° = 60°
