Question

35 POINTS!!!


What is the value of c? Assume that the line is tangent to the circle.


140


190


220


250

Answer 1

The 110 angle given is half the angle of the portion of the circle on the same side of the chord, so that portion of the circle opposite C is 110 x 2 = 220.

A full circle is 360 degrees, so C would be 360 - 220 = 140

C = 140

Answer 2

It would be 140, i dont think it would be 220
