It appears that you want to find the measure of angle ∠XYZ, but the information provided is unclear and seems to be missing critical context or a diagram. To determine the measure of an angle, we typically need additional information, such as the measures of other angles in a geometric figure or relationships between angles (e.g., supplementary, complementary, vertical angles, etc.).
Could you please provide more context or details about the problem, such as a diagram or any relationships between the angles?
