Question

1. The angles of quadrilateral are in the ratio 3:5:9:13. Find all the angles of the quadrilateral​

Answer 1

Let the angles of the quadrilateral be 3x, 5x, 9x, and 13x.

Sum of angles of a quadrilateral = 360°

ATP,

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

30x = 360

x= 12

Angles of a quadrilateral are 36°, 60°, 108°, and 156°.

Answer 2

Answer:

let the angels be 3x,5x,9x,13x

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

X=12

since

angle 3x=3*12=36degree

angle 5x=5*12=60degree

angle. 9x=9*12=108degree

angle 13x=13*12=156degree
