Answer: Assuming that 256 degrees is the measure of the intercepted arc, the measure of the tangent-choice angle is 128.

When you have a chord and tangent in a circle, they arc between them is called the intercepted arc. The measure of the angle formed by the tangent and chord is always have of the arc length.

256 / 2 = 128 degrees
