7.855 mm maybe the answer unless rounded to the tenths place to be 7.9 mm.
Answer:
The width of the river is about 8.39 m.
Step-by-step explanation:
Tan = Opposite/Adjacent
The width of the river is the side of a right triangle opposite the angle of 40°. The 10 m distance is the length of the side adjacent to the measured angle. So, we have ...
tan(40°) = width/(10 m)
Multiplying by 10 m, we get ...
width = (10 m)tan(40°) ≈ 8.39 m
The width of the river is about 8.39 m.
