Answer:

A) 1/2(238-x) = 58

Step-by-step explanation:

When an angle is formed by two secants, a tangent and a secant, or two tangents of a circle, the measure of this angle is one-half of the difference between the intercepted arcs.

In this circle, the intercepted arc measures are 238° and x°.  Their difference would be (238-x).  One-half of this would be 1/2(238-x).  This is equal to the angle measure, which is 58°.  This gives us the equation

1/2(238-x) = 58

Answer:

The answer is A, 1/2(238-x)=58
