Question

the angle of a quadrilateral are in the radio :3:5:9:13 find the angle of quadrilateral​

Answer 1

Step-by-step explanation:

let the angles be 3x, 5x, 9x, 13x.

angle sum of a quadrilateral= 360

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

30x=360

x=360/30

x=36/3

x=12

therefore, all the angles are:

3x=3*12=36°

5x=5*12=60°

9x=9*12=108°

13x=13*12=156°
