Question

angle of a quadriateral are 2:4:5:7. Find the angle​

Answer 1

Answer:

40,80,100,140 are angles of quadrilateral

Step-by-step explanation:

let the angles be x

then, 2x+4x+5x+7x=180°

18x=360

x=20°

Answer 2

Answer :

2:4:5:7

Let x be the common multiple.

2x + 4x + 5x + 7x = 360°

sum of all angles in a quadrilateral is 360°

18x = 360

x= 20

therefore, 2x = 2×20 = 40, 4x = 4×20 = 80, 5x = 5×20 = 100, 7x = 7×20 = 140.

40,80,100,140 are angles of a quadrilateral.
