so you know this is one of the "special triangles." Its angle measures are 30°, 60°, and 90°. The smallest angle (W) is opposite the shortest side (7).
The angle measures are ...
m∠U = 60°
m∠W = 30°
[the UW measure is correct]

Your calculator can tell you the arctangent of √3 or 1/√3. Be sure to set it to degrees mode.
