Question

the angles of a quadrilateral are 3x,4x,5x and 6x.find x.what are the angles in degree

Answer 1

We know sum of Angles of a quadrilateral is 360 degree

$3x + 4x + 5x + 6x = 360 ^{0}$

$18x = 360 ^{0}$

$x = 20 ^{0}$

so,Angles are

3x=60 degree

4x=80 degree

5x=100 degree

6x= 120 degree
