For this question, we use the Pythagorean theorem.

a^2+b^2=c^2

We know the lengths of the legs, a and b.
a=3
b=4

Now, let's solve for the hypotenuse, c.

3^2+4^2=c^2
25=c^2

Take the positive square root.

\boxed{c=5}

Hope this helps! :)

PLEASE HELP ME . how can the converse of the Pythagorean theorem help you determine whether the roped off area is in the shape o
trapecia [35]

Step-by-step explanation:

From the Pythagorean theorem we have:

a^2+b^2=c^2           <em>subtract b² from both sides</em>

a^2=c^2-b^2\to a=\sqrt{c^2-b^2}

Same:

b=\sqrt{c^2-a^2}
