Line BC is tangent to the circle centered at A. Find the measure of angle BCA. Explain or show your reasoning. 57° Angle CBA measures [ Select ] degrees, because tangent lines are [ Select] to a radius drawn to the point of tangency. The measures of the angles in a triangle add up to ( Select] |degrees, so we can subtract 57 and 90 from 180 to find that the measure of angle BCA is [ Select ) degrees.
