To determine The measure of the angle ∠ C A B . Explanation Obtain the measure of the angle ∠ C A B as follows. It is known that a tangent perpendicular to the radius at the point of tangency, then the angle is 90 ° . Here, as the tangent BT is perpendicular to the radius OB at the point of tangency, then the angle ∠ A B T = 90 ° . It is given that the angle ∠ A B C = 65 ° . Obtain the angle ∠ C B T as follows. ∠ A B T = ∠ C B T + ∠ A B C ∠ C B T = ∠ A B T − ∠ A B C
