Question

there four angel of quadrilateral are in the ratio of 3:7 7:9 find the angel of quadrillateral
​

Answer 1

Answer:

let the angle be x

3:7:7:9

3x+7x+7x+9x=180

26x=180

x=180/26

x= 6.9

put the values now

Answer 2

Step-by-step explanation:

angle 1 = 3 x

angle 2 = 7 x

angle 3 = 7 x

angle 4 = 9 x

angle 1 + angle 2 + angle 3 + angle 4 = 360°

3x + 7x +7x + 9x = 360°

26 x = 360°

x= 360/26

x = 14

angle 1 = 3 × 14 = 42

angle 2 = 7 × 14 = 98

angle 3 = 7 × 14 = 98

angle 4 = 9 × 14 = 126
