Answer:
50, 70, 150, 100 are the angles of a quadrilateral
....
Explanation:
Given,
angles of quadrilateral are
x-10
x+20
2x+50
2x
we know...
sum of all angles of quadrilateral is 360.
so
x-10+x+20+2x+50+2x=360
6x+60= 360
6x=300
x=50
now,
angles are_x-10= 50-10= 40
x+20= 50+20= 70
2x+50= 2× 50+50= 150
2x= 2× 50= 100
