Question

HEEEELLLLPPPPPP PLEASE IM STRUGGLING!!!

Answer 1

Answer:

8.55 ft

Step-by-step explanation:

These two triangles are similar, which means that the ratio of their corresponding sides will be the same.

The height of the 4-foot ladder and the height of the 9-foot ladder correspond, while the length of the 4-foot ladder corresponds to the length of the 9-foot ladder. So, we can write the ratio:

$\frac{3.8}{x} =\frac{4}{9}$, where x is the height of the 9-foot ladder.

Cross-multiply:

4 * x = 3.8 * 9

4x = 34.2

Divide by 4:

4x/4 = 34.2/4

x = 8.55

Thus, the height of the 9-foot ladder is 8.55 feet.

Hope this helps!

Answer 2

Simple... 3.8 / 4 + .95, and thats for every foot of a ladder...

so .95 x 9 = 8.55
