Answer 1

Answer:

20

Step-by-step explanation:

To solve this problem use proportions. The tree's proportion is equal to $\frac{30}{40}$ and the shed's proportion is $\frac{15}{x}$. These proportions are made by putting the height of the object over the length of the shadow. Then, cross multiply to find x. Do this by multiplying $30 *x$ and $40*15$. Next set these equal to each other, $30x=600$. Finally, divide both sides by 30 to find x. This equals 20 feet.
