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