To determine the measure of ∠XYZ, we need more information about the angles or the context in which they appear. The responses provided (24°, 136°, and 90°, along with the repetition of 24° and 136°) suggest that this may be a question related to a geometric figure, such as a triangle or another shape.
If you have a specific geometric context or additional information (like the total degrees in a triangle, supplementary angles, etc.), please provide it, and I can help you find the measure of ∠XYZ.
