Question

The four angles of a quadrilateral are in a ratio of 3:5:9 find the angles

Answer 1

Answer:

1x+3x+5x+9x=360

18x=360

x=360/18

x= 20

Hope it helps you

Answer 2

Answer:

ratio of the angles of triangle

=1:3:5:9

Sum of all angles of quadrilateral is 360

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

=18x=360

X=360/18

=20

Angles of quadrilaterals are the following

1)x=20

2) 3x=3(20)=60

3) 5x=5(20)=100

4) 9x=9(20)=180
