Question

The four angles of a quadrilateral are as 3 ratio 5 ratio 7 ratio 9 find the angles

Answer 1

let all ratios be
3x 5x 7x and 9x
now
3x+5x+7x+9x=360 deg.
24x=360 deg.
x=15
now 3x = 45
5x=75
7x=105 and
9x=135

Answer 2

Let angle are 3x,5x,7x,9x. Now 3x+5x+7x+9x=360. Asp of quadrilateral so, 24x=360, X=15 angles are 3x15=45, 5x15=75, 7x15=105,9x15=135
