Question

O is the centre of this circle.

Determine the value of cº.

A. 180
B.94
C.90
D.47

Answer 1

D. 47

Angle T is an inscribed angle. An inscribed angle is half of the center angle. So since angle O, the center angle, equals 94, you have to divide it by two. And when you do 94/2, it would equal to 47. Making c equal to 47 degrees.
