Question

THE ANGLE OF A QUADRILATREL ARE IN RATIO 3:5:9:13 FIND THE ANGLES OF QUADRILATREL

Answer 1

Answer:

3x+5x+9x+13x = 360

30x = 360

X= 12°

3x=36°

5x=60°

9x=108°

13x=156°

Answer 2

Answer:

let the common factor of ratio be x

3:5:9:13 is 3x,5x,9x,13x

So,

3x+5x+9x+13x=360. (angle sum property of

quadrilateral)

30x=360

x=360/30=12

x=12
