Question

Radio of angles =3:5:9:13

Answer 1

Answer:

Let the common ratio between the angles be = x. As they are in ratio 3 : 5 : 9 : 13, so we can assume angles be as 3x, 5x, 9x and 13x. Hence, the angles of quadrilateral are 36°, 60°, 108° and 156°

Answer 2

3:5:9:13 = 360
3n + 5n + 9n + 13n = 360
30n = 360

n = 360/30 = 12

3n = 36

5n = 60

9n = 108

13n = 156
