Question

In a quadrilateral ABCD, the angles A, B, C and D are in the ratio 1: 2: 3: 4. Find the measure of greatest angle of the quadrilateral.
​

Answer 1

Answer:

let all digits be

1x 2x 3x 4x

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

10x = 360

x = 360/10

x=36 degree

we can see 4x is greatest

so,

4 * 36

144 degree
