Answer:
Last option: 63
Step-by-step explanation:
You need to observe and analize the triangle <em>XWZ </em>provided in the image attached.
You can observe that the lenght of the side <em>XW </em>of the triangle <em>XWZ</em> is congruent to the lenght of the side <em>ZW</em>. This means that the lenght of the side <em>XW </em>and the lenght of the side <em>ZW</em> are equal.
Therefore, if the measure of the angle ∠<em>X</em> is 63, then the measure of the angle ∠<em>YZW</em> is 63:
This matches with the last option.
