Question

Three angles of quadrilateral
are in the ratio of 2 is to 5 to 6 is the fourth angle measures 100 degrees find the other three angles of quadrilateral.​

Answer 1

Answer:

let 1 st angle be 2x

let 2nd angel be 5x

let 34 rd angel be 6x

4th angle = 100

atq - 2x +5x + 6x + 100 = 360 ( the sum of all angels of a quadrilateral is 360 )

13x =360-100

13x = 260

x = 260 / 13

x = 20

1st angle = 2× 20 = 40

2nd angle = 5 × 20 = 100

3rd angle = 6 × 20 = 120
