Answer:
142 yards.
Step-by-step explanation:
See the attached diagram.
Let the reservoir is AC and Howard is standing at B and AB = 91 yards.
Now, the angle of elevation from B to the top of the reservoir C is 50°.
Then using trigonometry,
⇒
≈ 142 yards.
Therefore, the distance of Howard from the top of the reservoir is 142 yards. (Answer)
8h=6h-14
subtract 6h from both sides
2h=14
divide by 2
h=7
