Question

AC is tangent to circle O at A. BA is the diameter of circle O. Point o is in the middle of BA
If mBY = 68°, what is m∠YAC? (1 point) Responses 56° 56 degree 58° 58 degree 62° 62 degree 22° 22 degree

Answer 1

The measure of angle YAC is equal to half the measure of arc BY. Since mBY = 68°, the measure of angle YAC is 68°/2 = 34°.

Therefore, the correct answer is not among the provided options. The correct measure of angle YAC is 34 degrees.
