In triangle UVW, the measure of W=90°, WU = 35 feet, and UV = 92 feet. Find the measure of ZU to the nearest tenth of a degree.

Use stokes' theorem to evaluate c f · dr where c is oriented counterclockwise as viewed from above. f(x, y, z) = xyi + 5zj + 7yk, c is the curve of intersection of the plane x + z = 8 and the cylinder x2 + y2 = 81.
