Answer:

m∠U = 104°

Explanation:

If in triangle UVW, UV ≅ WU, then ΔUVW is an isosceles triangle.

The congruent base angles are ∠V and ∠W, so m∠V = m∠W.

Interior angles of a triangle sum to 180°:

⇒ m∠U + m∠V + m∠W = 180°

Given m∠W = 38°:

⇒ m∠U + 38° + 38° = 180°

⇒ m∠U + 76° = 180°

⇒ m∠U = 104°
