1. Problem Description
We are given a circle with two intersecting chords, and . We are given that and . We want to find , where is formed by the intersection of the two chords.
2. Solution Steps
We can find the measure of angle 1 using the following formula:
Since is an inscribed angle that intercepts arc , .
Since is an inscribed angle that intercepts arc , .
Also and are vertical angles, so the arcs can be and
, because both are inscribed angles that intercept arc .
.
.
Another approach: Since is an exterior angle of , its measure is equal to the sum of the measures of the two non-adjacent interior angles. Thus, .
