Answer:

Step-by-step explanation:

The formula for the Pythagorean Theorem is:

$\sqrt{a^2+b^2}=c$

Now,

A=7

B=24

7x7=49

24x24=576

Add,

576+49=625

Last,

Take the square root of 625

The square root of 625 is 25

c=25

To Check if the hypotenuse is correct:

$a^2+b^2=c^2$

$7^2+24^2=25^2$

7x7=49

24x24=576

25x25=625

49+576=625

625=625,

Therefore the hypotenuse is 25.
