Answer: approximately 29 feet

Explanation: You need to find a tree so that the angle of elevation from the end of the shadow to top of the tree is 40 degrees.

The length of the shadow is an adjacent side and is 35.
The height of the tree is the opposite side.  You could use X.

Tan ratio = opposite/adjacent

tan(40) =  x/35
x = 35*tan(40) =29.37

On a farm there was a cow. And on the farm there were 2 sheep. There were also 3 chickens. What is the total mass of the 1 cow,
RoseWind [281]

The total mass of the living things on the farm is 588 kg.

<h2><u>Mass calculation</u></h2>

Since on a farm there was a cow, 2 sheep and 3 chickens, to determine what is the total mass of the 1 cow, the 2 sheep, the 3 chickens, and the 1 farmer on the farm, the following calculation must be performed :

  • (6.2 x 10) + (4 x 10 x 10) + (2 x 6 x 10) + (3 x 2 x 1) = X
  • 62 + 400 + 120 + 6 = X
  • 588 = X

Therefore, the total mass of the living things on the farm is 588 kg.

Viktor [21]

<u>Given:</u>

The angle of elevation from the point on the ground to the top of the tree is 34° and the point is 25 feet from the base of the tree.

We need to determine the height of the tree.

<u>Height of the tree:</u>

Let the height of the tree be h.

The height of the tree can be determined using the trigonometric ratio.

Thus, we have;

tan \ \theta=\frac{opp}{adj}

Substituting the values, we get;

tan \ 34^{\circ}=\frac{h}{25}

Multiplying both sides by 25, we have;

tan \ 34^{\circ} \times 25=h

 0.6745 \times 25=h

       16.8625=h

Rounding off to the nearest tenth of a foot, we get;

16.9=h

Thus, the height of the tree is 16.9 feet.

Hence, Option B is the correct answer.
