Question

The measure of is 256. what is the measure of xzw, the tangent-chord angle?

a. 166
b. 138
c. 256
d. 128

Answer 1

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
