Finding the missing side of a right triangle is a pretty simple matter if two sides are known. One of the more famous mathematical formulas is \(a^2+b^2=c^2\), which is known as the Pythagorean Theorem. The theorem states that the hypotenuse of a right triangle can be easily calculated from the lengths of the sides. The hypotenuse is the longest side of a right triangle. If you're given the lengths of the two sides it is easy to find the hypotenuse. Just square the sides, add them, and then take the square root.
Re: Difference between NOdup and NoDupkey..?? NODUP will delete duplicated observations (records that are identical to each other) while NODUPKEY will delete those observations that have duplicate BY values (the sort BY variables that you name in PROC SORT). From @Cynthia_sas: Here are just a few of the papers and Tech Support notes on the subject:
The Pixel C automatically detects whether the keyboard is attached and knows whether or not to show you the on-screen keyboard. The system is clever. Actually, itâs too clever by half. The Pixel C came with a cheeky little how-to card that explains how it works and, well, it needed it. Iâve watched no fewer than five Very Smart People who hadnât seen it before struggle to figure out how to work the thing.
