I found out how I was messing up and getting the wrong answer. I entered (30) squared + 49.5 squared then took the square root of the answer getting 39.37 instead of 57.88 which i figured out was the right answer, I didn't enter all in my calc at the same time. ...whoops. Thanks for all your help mathmate!

You're very welcome!
