Question

The angles of a quadrilateral are in the ratio 3 : 5 : 7 : 9. Find the angles of the quadrilateral.​

Answer 1

Answer:

45, 75, 105, 135

Explanation:

The angles of a quadrilateral are in the ratio 3 : 5 : 7 : 9

let the angles are 3x, 5x, 7x, 9x then

3x+5x+7x+9x = 360

24x = 360

x = 360/24 = 15

so angles are 3x = 3×15 = 45

5x = 5×15 = 75 , 7x = 7× 15 = 105

9x = 9×15 = 135
