Question

Can someone explain how to do this?

Answer 1

Answer:

The answer to your question is: 40°

Step-by-step explanation:

First the Δ UXW = is a right triangle, then the ∠ UXW = 90°

The sum of the internal angles in a triangle equals 180°

∠UXM = 180° - ∠XUW - ∠UWX

∠UXM = 180° - 90 - 50

∠UXM = 40°
