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.

Answer:
(4 - 
)(16 + 4 + 
)
Step-by-step explanation:
64 - 
← is a difference of cubes and factors in general as
a³ - b³ = (a - b)(a² + ab + b²), thus
64 -
= 4³ - ( )³
= (4 - )(4² + 4 + ( )² )
= (4 - )(16 + 4 + )
