The sector of a circle has radius of 14 cm and its perimeter 50 cm. Find its central angel? Options:
A) 180o
B) 225o
C) 270o
D) 150o
E) 90o
Lte central angle = x   Perimeter of the sector = length of the arc + 2(radius)   50= (x/360 * 2 * 22/7 * 14) + 2(14)   50 = 88x/360 + 28   88x/360 = 22   88x = 7920   x = 90   Answer: 90o
