Question

Three angles of quadrilateral are in the ratio 3:5:6 if the 4th angle is 80 degree find the majors of other three angles

Answer 1

Answer:

Let angles be :-

3x,5x,6x

We know the sum of all angles in quadrilateral is 360°

According to question:-

3x + 5x + 6x + 80° = 360°

14x + 80° = 360°

14x = 360° - 80°

x = 280° / 14

x = 20°

3x = 3 × 20° = 60°

5x = 5 × 20° = 100°

6x = 6 × 20° = 120°

Step-by-step explanation:

Hope this helps you.
