Answer:

<em>The distance from the flagpole to the tree is 27 ft</em>

Step-by-step explanation:

<u>Similar Triangles</u>

Since the elevation angle from which the trees cast their shadows has the same measure and given the tree and the flagpole and the ground form right angles, both triangles are similar.

Similar triangles have their corresponding side lengths proportional. The ratio between the distances from the bench to the tree and flagpole and their heights is constant, i.e.:

\displaystyle \frac{16}{18}=\frac{40}{x}

Where x is the distance from the bench to the tree.

Solving for x:

\displaystyle x=40\cdot \frac{18}{16}

x = 45 feet

Thus the distance from the flagpole to the tree is 45 - 18 = 27 feet

Step-by-step explanation:

Given:

Area of square land = 3,600 m²

Find:

Perimeter of his fence

Computation:

Area of square land = 3,600 m²

4a² = 3,600 m²

a² = 900 m²

a = 30 m

Perimeter of his fence = 4a

Perimeter of his fence = 4 x 30

Perimeter of his fence = 120 m
