Question

EXERCISE 8.1
The angles of quadrilateral are in the ratio 3:3:9:13. Find all the angles of the
guidnilateral​

Answer 1

Answer:

3+3+9+13=28.

3/28(360)....like this do for all

Answer 2

Answer:

Let the angles of quadrilateral = 3x,5x, 9x, 13x

= 3x+5x+9x+13x=360 ( angle sum property of a quadrilateral)

= 30x=360

x=360/30

x=12

therefore the angles are

3x=3*12=36

5x=5*12=60

9x=9*12=108

13x=13*12=156

therefore 36+60+108+156=360
