The legs of a right triangle are 3 and 4. Find the length of the hypnotuse.... Please explain!
Thanks in advance.

The hypotenuse is the longest side of a triangle and is opposite the right-angle in a right-angled triangle. From what you tell me, Phythagoras theorem shall be used here. Where:
c^2 = a^2 + b^2 (note, a b and c can be any value) in this case the c represents the hypotenuse (its the longest side)
so, you have 3 and 4 as the other lengths. THat means
c^2 = 3^2 + 4^2
= 9 + 16
= 25
c = sq. root 25
= 5
Happy to help!
Geometor is absolutely right, but i'd just like to point out that this is the famous 3-4-5 triangle, so with experience you would know that the answer is 5 without doing any calculations. it works for anything in propotion as well.
so if the legs were: 12 and 16, the answer for the hypotenuse would be 20, without even doing calculations (you can check this if you don't believe me)
