I think everyone's forgetting one very basic fact:
Make sure you have a right triangle! The pythagorean theorem only works with right triangles.
Other than that, follow what everyone else is telling you.
The Pyth. Thm is:
a^2 + b^2 = c^2
c^2, of course, is the hypotenuse.
It doesn't matter which of the other sides is a or b.
Le'ts make a=3 and b=8.
so
(3)^2 + 8^2 = c^2
9 + 64 = c^2
73= c^2
sqrt(73)= c
this is approximately 8.54 or something like that. I don't have a calculator.

Pythagorean theorem: a^2 + b^2 = c^2, where a and b are the legs and c is the hypotenuse.
3^2 + 8^2 = c^2
9 + 64 = c^2
73 = c^2
c = (sqrt)73

the formula to find hypotenuse is the square root of a^2 +b^2...
in this case 3^2 +8^2= 9+64=73 and the square root of 73 is approximatly 8.544

Is it a precise triangle? if so you should use the Pythagorean theorem. a^2 + b^2 = c^2 (a-squared plus b-squared = c-squared). a and b are the factors of the triangle and c is the hypotenuse (the side during from the main astounding perspective).

use the pythagorus theorem: a squared + b squared = c squared where a and b are the two "legs" of the triangle and c is the hypotenuse. that will give u 3 squared plus 8 squared = c squared.... then just do the math, take the square root of both sides and you'll have the value of c! good luck!

use a^2+b^2=c^2
hypontenuse=c
so 3=a and 8=b
3^2+8^2=c^2
9+64=c^2
73=c^2
square root both sides so
c=the square root of 73 or 8.544
but the square root of 73 is more exact

Pythagoras theorem states that if a, b represent the adjacents sides to the right angle, and the hypothenus is c, then
a^2+b^2=c^2
or simply
hypothenus
=c
=sqrt(a^2+b^2)
=sqrt(8^2+3^2)
=sqrt(64+9)
=sqrt(73)
=8.544 (approx.)

Pythagorean Teorem
c² = a² + b²
c² = √(3)² + (8)²
c ² = √9 + 64
c² = √73
c = 8.544003745
The answer is c = 8.544 rounded to three decimal places.
The Hypotenuse is 8.544

[Length of hypotenuse]^2 = [base length]^2 + [side length]^2
for your problem it will be 73^.5
