Question

The angles of a quadiateral in the 3:5:9:13. Find the angles in the quadiateral

Answer 1

Answer:

let,the angle of quadrilateral be 3x,5x,9x and 13x

Now according to question

3x+5x+9x+13x=360°

or,30x=360°

or,x=360/30

or,x=12°

Now,

3x=12×3=36°

5x=5×12=60°

9x=9×12=108°

13x=13×12=156°
