Marina CMI [18]

Answer:

The option <u> J 36.7 inches</u>  best represents the length of hypotenuse.

Step-by-step explanation:

<u><em>The question is incomplete, so below is the complete question:</em></u>

A triangle has one leg of 32 inches and one leg of 18 inches. For the triangle to be a right triangle, which best represents the length of the hypotenuse?

F 34.2 inches  G 36 inches  H 41.8 inches  J 36.7 inches.

Now, to find the hypotenuse.

Leg 1 = 32 inches.

Leg 2 = 18 inches.

Now, to get the hypotenuse we use pythagoras theorem:

(Leg1)^2+(Leg2)^2=(Hypotenuse)^2

(32)^2+(18)^2=(Hypotenuse)^2

1024+324=(Hypotenuse)^2

1348=(Hypotenuse)^2

Using square root on both sides we get:

36.7=Hypotenuse

Hypotenuse=36.7\ inches.

Therefore, the option J 36.7 inches best represents the length of hypotenuse.
