Question

if the angle of a auadrilateral are in the ratio 3:5:9:13then find all the angles of the quadrilateral.

Answer 1

Hi Friend !!!

=================


let the angles in a quadrilateral be

3x , 5x , 9x , and 13x

The sum of all angles in a quadrilateral = 360

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

30x = 360

x = 360/30

x = 12

then the angles are.

3x = 3×12 = 36

5x = 5×12 = 60

9x = 9×12 = 108

13x = 13×12 = 156

Hope it helps u :-)

Answer 2

let the angles of the quadrilateral be
3x,5x,9x and 13x
we know that sum of all angles of a quad.is 360degree
therefore,
3x+5x+9x+13x=360
30x=360
x=360/30
x=12
therefore
3x=3×12=36
5x=5×12=60
9x=9×12=108
13x=13×12=156
