AC is tangent to circle O at A. The diagram is not drawn to scale. If mBY = 34 degrees, what is < YAC?
68 degrees, 51 degrees, 73 degrees, 56 degrees

Solution:

From the diagram, we can say that the angle BAC is 90 since AC is the tangent to the given circle.

Given that BAY is 34

BAC = BAY + YAC = 90

34 + YAC = 90

YAC = 90 - 34

YAC = 56.

AC is tangent to circle O at A. The diagram is not drawn to scale. If mBY = 34 degrees, what is < YAC?

Summary:

AC is tangent to circle O at A. The diagram is not drawn to scale. If mBY = 34 degrees, then YAC = 56.
