Answer:
8.39 meters
Step-by-step explanation:
The angle is opposite the side of interest of the right triangle representing the geometry. The adjacent side is known, so the tangent function can be useful.
Tan = Opposite/Adjacent
tan(40°) = width/(10 m) . . . . . filling in given values
(10 m)·tan(40°) = width ≈ 8.390996 m ≈ 8.39 m
The width of the river is about 8.39 meters.
