Question 251473
The hypotenuse is the longest side of a right triangle.
so either the missing side is the hypotenuse or the 8 cm side is.
If the missing side is the hypotenuse, it won't be the shortest length possible.
8*8=6*6+b^2
64=36+b^2
28=b^2
sqrt(28)=b
we can only use the positive result
2sqrt(7)=b
5.2915=b
