Question

The angles of a quadrilteral are in the ratio 3: 4: 6 :7 find the measures of the angles.(hint the sum of the angles of quadrilateral is 360°.)?

Answer 1

let the angles be 3x, 4x, 6x and 7x.

sum of angles of quadrilateral= 360°

3x+4x+6x+7x = 360°
20x= 360°
x= 18°

so 3x= 54°
4x= 72°
6x= 108°
7x= 126°
