Question

solve this .. please

Answer 1

Let the angles be 3x, 5x, 9x, 13x

ATQ :
3x+5x+9x+13x=360
30x=360
x=360/30
x=12

3x=3×12=36
5x=5×12=60
9x=9×12=108
13x=13×12=156

All the angles of the quadrilateral are 36°,60°,108°and 156°

Answer 2

Hi,

In a quadrilateral, the sum of angles is always 360 degrees.

Let the angles be 3x, 5x, 9x, 13x respectively.

Sum of angles = 360 degrees

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

=> 30x = 360

=> x = 12

So,

The angles are 36, 60, 108 and 156 degrees respectively.

Hope it helped :-)
