The definition of the tangent function tells you
tan(angle) = (300 ft) / (distance to mountain)
This equation can be rearranged to
(distance to mountain) = (300 ft) / tan(angle)
For the far end of the river,
distance to far end = (300 ft) / tan(24°) ≈ 673.8 ft
For the near end of the river
distance to near end = (300 ft) / tan(40°) ≈ 357.5 ft
Then the width of the river can be calculated by finding the difference of these distances:
width of river = distance to far end - distance to near end
width of river = 673.8 ft - 357.5 ft
width of river = 316.3 ft
The appropriate answer choice is
316 ft.

Answer: Yes
The point (-8,4) makes the inequality true
==================================================
Explanation:
We have x = -8 and y = 4 pair up together due to the point (x,y) = (-8,4).
Let's plug these values into the inequality
The last inequality is true because -80 is to the left of 19 on the number line. So -80 is smaller than 19.
Since the last inequality is true, this means the first inequality is true when (x,y) = (-8,4).
