From the description, triangle ABC is a right triangle, because AC is a radius to tangent BC; a radius to a point of tangency is perpendicular to the tangent.

So angles CBA and ACB are the acute angles of a right triangle and so are complementary. Given that the measure of angle CBA is 14 degrees, the measure of angle ACB is 90-14 = 76 degrees.
