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
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
