Solution:

In this problem, $\overline{VR}, \overline{VZ},$ and $\overline{ZR}$ are midsegments of $\triangle UWY$.

Key Properties of Midsegments in a Triangle:

1. A midsegment is parallel to one side of the triangle and half its length.
2. The angles formed by the midsegments correspond to the angles of the triangle because the midsegments divide the larger triangle into smaller similar triangles.

Given:

• $\angle YZR = 44^\circ$,
• $\angle ZRW = 76^\circ$,
• We are to find $x = \angle RVZ$.

Step-by-Step Solution:

1. Find $\angle YZR + \angle ZRW$: $\angle YZR + \angle ZRW = 44^\circ + 76^\circ = 120^\circ$

2. Calculate $\angle YRW$: In $\triangle YRW$, the sum of the angles is $180^\circ$. Thus: $\angle YRW = 180^\circ - 120^\circ = 60^\circ$

3. Use Triangle Similarity: Since $\overline{VR}, \overline{VZ},$ and $\overline{ZR}$ are midsegments, $\triangle ZRV$ is similar to $\triangle UWY$. This means that the angles of $\triangle ZRV$ correspond to the angles of $\triangle UWY$.

4. Find $\angle RVZ = x$: Since $\angle RVZ$ corresponds to $\angle YRW = 60^\circ$, we conclude: $x = 60^\circ$

Final Answer:

$x = 60^\circ$
