A%5E2%2BB%5E2=C%5E2
3%5E2%2B5%5E2=C%5E2
9%2B25=C%5E2
C=sqrt%2834%29
Use a calculator to get the appropriate decimal places.

this is the pythagrium theorem.
You can solve it by using:
c^2=a^2+b^2
c^2=9+25
c=17

IN THE RIGHT TRIANGLE FIND THE LENGTH OF THE SIDE NOT GIVEN USE A CALCULATOR TO FIND AN APPROXIMATION TO THE DECIMAL PLACES.
A=3 B=5
THE VALUE OF C IS
(ROUND TO NEAREST THOUSANDTH)
----------------
You have to specify if the side is the longest, the hypotenuse, or if 5 is the hypotenuse. Either way, use the Pythagorean Theorem, named for Pythagoras.
-----------
If 5 is the long side:
a%5E2+%2B+s%5E2+=+b%5E2
9+%2B+s%5E2+=+25
s%5E2+=+16
s = 4
---------
If the missing side is the hypotenuse:
c%5E2+=+a%5E2+%2B+b%5E2
c%5E2+=+3%5E2+%2B+5%5E2
c%5E2+=+34
c =~ 5.831
===================
It's not 17. You can't make a triangle with sides of 3, 5 & 17.
