Question
If the angles of a quadrilaterals are in the ratio of 1:2:4:5, find the angles.

Please Answer It.​

Answer 1

Answer:

let the angles of a quadrilateral be x, 2x, 4x, and 5x.

then we know that sum of all angles of a quadrilateral is 360°

so,

x+2x+4x+5x = 360°

12x =360°

x= 30°

now , 2x =2×30 =60°

4x =4×30=120°

2x=2×30=60°

5x=5×30°=150°

hope it will help....
