Question

Four angles of a quadrilateral are in the ratio 7: 8:10:11 find there measure
​

Answer 1

Lets take the angles as =7x,8x,10x,11x

According to the question, sum of these angles =360

= 36x=360

=x=10

So angles are = 70°,80°,100°,110 °

Answer 2

7x+8x+10x+11x=360(sum of all the angles of quadrilateral)

36x=360

x=10

7x=70

8x=80

10x=100

11x=110
