Question

The four angles of a quadrilateral are in the ratio 2:5:6:7
Find the smallest angle in the quadrilateral

Answer 1

Step-by-step explanation:

let the angle be x

then ,

2x + 5x + 6x + 7x = 360

20 x = 360

x = 360/20

× = 18

then 2x = 2 × 18 = 36

5x = 5 × 18 = 90

6x = 6 × 18 = 108

7x = 7×18 = 126

hence the smallest angle is 36
