Question 467773
If an angle’s vertex is outside of a circle (and
its rays intersect the circle in two distinct
places), then the angle intercepts two arcs. If
you take the positive difference of these arc
measures and divide by two, you will find the
measure of the angle.

{{{(x-"48°")/2="55°"}}}

{{{x - "48°" ="55°"}}}

{{{x = "103°"}}}
