Question

Angles of quadrilateral are (4x), 5(x+2), (7x-20) and 6(x+3) Find; the value of x , each angle of quadrilateral (class 6) ans in brife

Answer 1

Angle sum of quadrilateral is 360degrees
4x+5x+10+7x-20+6x+18=360
22x+8=360
x=16
First angle=4x=64 degrees
5x+10=90 degrees
7x-20=92 degrees
6x+18=114 degrees

Answer 2

4x+5x+10+7x-20+6x+18=360 degree
22x+ 8=360 degree
22x=360-8
x=352÷22
x=16

4x=64 degree
5(x+2)=90 degree
(7x-20)=92 degree
6(x+3)=114 degree

sum of qudrilateral is of all angles is 360 degree.
