1. Problem Description
The problem asks to solve for given the expressions for the measures of the angles in a quadrilateral inscribed in a circle, where two angles are and and another one is . Because the quadrilateral is inscribed in a circle, the sum of opposite angles equals 180 degrees.
2. Solution Steps
Let the four angles of the quadrilateral be and . We are given that , , and . Since the sum of angles in a quadrilateral is 360 degrees, . Also, opposite angles of a cyclic quadrilateral are supplementary, i.e., add up to 180 degrees.
We have two cases:
Case 1: and are opposite angles. Then , so , i.e., .
Case 2: and are opposite angles. Then , so , i.e., .
In Case 1, .
.
.
In Case 2, .
.
.
Since the problem has right angle symbols where they meet at the center of the circle, this implies that the angles and are opposite angles. Thus,
.
.
.
.
