If the two legs a and b of a right triangle are 30 and 40, then the hypotenuse c is:
c%5E2+=+a%5E2+%2B+b%5E2
c%5E2+=+30%5E2+%2B+40%5E2
c%5E2+=+900+%2B+1600
c%5E2+=++2500
c+=++sqrt%282500%29
highlight%28c+=++50%29

the hypotenuse=50 because this is a 3x4x5 right triangle.
proof.
30^2+40^2=50^2
900+1600=2500
2500=2500
