Take the sides in proportion.

⇒ $\frac{AE}{AD} =\frac{AB}{AC}$

⇒ $\frac{12}{12+8} =\frac{x}{15}$

⇒ $\frac{12}{20} =\frac{x}{15}$

⇒ $\frac{3}{5} =\frac{x}{15}$

⇒ $3 = \frac{x}{3}$

⇒ x = 3 × 3

⇒ x = 9

Answer:

$h= 126.33\ yd$

Step-by-step explanation:

Let h be the height of the tree.

Given:

Height of the tree = 379 feet

We need to find the height of the tree in yards.

Solution:

From the given statement, Hyperion is the tallest tree in the park, with a height of approximately 379 feet,

We need to convert the height of the tree from feet to yard. So, We divide the height of the tree by three for yard.

For one feet

$h = \frac{1}{3}\ yd$

For 379 feet

$h = \frac{379}{3}\ yd$

$h= 126.33\ yd$

Therefore , height of the tree $h= 126.33\ yd$
