1. Problem Description
We are given a quadrilateral with , , and . We are asked to find the obtuse angle .
2. Solution Steps
First, let's find the angle . Since the sum of angles in a triangle is , we can find in .
We know that , and .
Let . The sum of the interior angles in a quadrilateral is .
Thus, .
However, we want the obtuse angle , so we calculate .
is the reflex angle, which is . The other angle is . We want the obtuse angle, so the required angle is .
3. Final Answer
The answer is C.
