Question

three angles of a quadrilateral are in the ratio of 3:5:6. if the fourth angle is 80 degree, find the other angles of the quadrilateral.

Answer 1

If The angles are in 3:5:6 ratio then the angles can be written as:

3x,5x and 6x

In A Quadrilateral The Sum of all angles is 360

So,

3x+5x+6x+80=360

14x+80=360

14x=280

x=20

So, The Other Angles Are

3x=3(20)=60

5x=5(20)=100

6x=6(20)=120

Therefore The Other angles are 100,120and 60

Hope THIS ANSWER might help

Answer 2

6:5:3

6x, 5x, 3x

6x+5x+3x+80=360

14x+80= 280

20

3x= 3x20=60

6x=6x20=120

5x=5x20=100 Ans
