An engineer needs to determine the distance across a river without swimming to the other side. The engineer notices a tree on th
nasty-shy [4]

Answer:

Step-by-step explanation:

The engineer can use a clinometer to measure the angle of elevation of the top of the tree. Let the height of the tree be represented by x, the she could determine the distance across the river, d, by applying the trigonometric function.

Tan θ = \frac{opposite}{adjacent}

           = \frac{x}{d}

the the distance, d = x ÷ Tan θ

Assume the angle of elevation of the top of the tree is 30^{o}, and the height of the tree is 10 m, then the distance, d, across the river would be;

d = \frac{10}{0.5774}

  = 17.3190

d = 17.32 m

The sketch to the explanation is attached to this answer for more clarification.

solong [7]
The ratio of the areas is 340/1158 = 170/579thus the ratio of the side lengths is sqrt(170)/sqrt(579)  = .5418the ratio of volumes is the side length ratio cubed = .5418^3 = .159Volume of smaller solid  = (.159)(1712) = 272.37
