Answer:

x=187

Explanation:

Use the exterior two secant intersecting theorem,

The Outside Angles Theorem states that the measure of an angle formed by two secants, two tangents, or a secant and a tangent from a point outside the circle is half the difference of the measures of the intercepted arcs.

In other words,


(x - 97)/(2) = 45


x - 97 = 90


x = 187
