Answer 2

What we have here is an angle formed by two secants outside of a circle. In order to find the measure of the angle outside, you take the difference of the two arcs subtended by the angle and divide by two.

In this case, we have the measure of the angle, and are missing one of the arcs, so we just have to rearrange the equation a bit.

It looks like this:
(110-x)/2=25 (apologies for weird formatting, connection issues)
Now that we know that, it's a simple algebra problem.
x=60
