Question

find x in following figure

Answer 1

x is 50 degrees (90+90+60 +70+50= 360(exterior angle)

Answer 2

Sum of the exterior angles of an regular polygon = 360 degree
So, angle A+ B+C+D+E= 360 degree
A+ B+C+D+E= 360
90 dgree+60 dgree + 90 dgree + 70 dgree+ x= 360 dgree
310 dgree + x = 360 dgree
x = 360 dgree - 310 dgree
x = 50 dgree
