Dmitry [639]

Answer:

40 ft

Step-by-step explanation:

The fiagram shows the right triangle (one angle is right angle).

By the Pythagorean theorem,

$\text{Leg}_1^2+\text{Leg}_2^2=\text{Hypotenuse}^2$

From the diagram,

$\text{Leg}_1=24\ ft\\ \\\text{Leg}_2=32\ ft\\ \\\text{Hypotenuse}=c\ ft,$

then

$24^2+32^2=c^2\\ \\c^2=576+1,024\\ \\c^2=1,600\\ \\c^2=40^2\\ \\c=40\ ft$
