Question

The angles of quadrilateral are in the ratio 3:5:9:13.Find

Answer 1

Answer:

Let the ratio of angle be 3x:5x:9x:13x

We know that the sum of interior angles of a quad. is 360°

A/q

3x + 5x + 9x + 13x = 360°

=> 30x = 360°

=> x = 360°/30

=> x. = 12

Hence,

1st angle = 3x = 3×12 = 36°

2nd angle = 5x = 5 × 12 = 60°

3rd angle = 9x = 9× 12 = 108°

4th angle = 13x = 13 × 12 = 156°
