In the diagram of circle o, what is the measure of < abc?

The angle formed by the intersection of 2 tangents outside the circle equals half the difference of the intercepted arcs.

near arc = 150°
far arc = 360 - 150 = 210°

m∠ABC = (210 - 150)/2 = 30°

The answer would be d i think but i’m for sure it is not a and c

The coordinates of point a right now is (-3,-1) you have to multiply these coordinates by a factor of 2 to get (-6,-2)
