If a 12ft tree casts a 17ft shadow, what tree height will cast a 28 ft shadow?

12/17 = x/28

Cross multiply and solve for x.

Could the answer be 23

To determine the height of the tree that will cast a 28 ft shadow, we can use a proportion.

A proportion is an equation that states that two ratios are equal. In this case, we can set up the proportion:

(height of the tree) / (length of the shadow) = (height of the 12ft tree) / (length of the 17ft shadow)

Let's assign variables to the values in our proportion. Let's say "x" represents the height of the tree we want to find, and "28" represents the length of the shadow we want to determine.

So our proportion becomes:

x / 28 = 12 / 17

To solve for x, we can cross-multiply:

17x = 12 * 28

17x = 336

Now, divide both sides of the equation by 17 to isolate x:

x = 336 / 17

Using long division or a calculator, we find that x is approximately equal to 19.7647.

Therefore, a tree with a height of approximately 19.7647 feet will cast a 28 foot shadow.
