Answer: Question #1 The height of the tree is about 18 feet.

To solve this problem, you have to write a proportion using the similar triangles that are drawn. The height of the tree matches the height of the person and the shadows match.

Therefore, we can write and solve the following equation:

x/15 = 5.5/4.5
82.5 = 4.5x
x = 18.33

Find the slope of the line that passes through (2,21) and (84, -30)

Flura [38]

Answer:

-51/82.

Explanation:

Given two points (x1,y1)=(2,21) and (x2,y2)=(84,-30), we find the slope using the formula below:

$m=\frac{y_2-y_1}{x_2-x_1}$

Substitute the given points:

$\begin{gathered} m=\frac{-30-21}{84-2} \\ m=-\frac{51}{82} \end{gathered}$

The slope of the line that passes through the given points is -51/82.
