Question

if the angles of a quadrilateral are in ratio 1:2:3:4 find the angles
​

Answer 1

Answer:

let the angles be 1x,2x,3x,4x

1x+2x+3x+4x=360

10x=360

x= 360/10

x= 36

Answer 2

Let the angles of quadrilateral be

x, 2x, 3x , 4x

sum of all angles of quadrilateral = 360°

x + 2x + 3x + 4x = 360°

10x = 360°

x = 360/10 = 36°

Ans. the four angles are :-

x = 36°

2x = 2 × 36 = 72°

3x = 3 × 36 = 108°

4x = 4 × 36 = 144°
