Question 551114: In a 3-D setting:
Given 1 leg and the Hypotenuse, calculate the missing leg. HOW TO DO!?!
I was out sick from school right before winter break and I missed an exam! I completely forgot! Then on the Thursday that I returned on, I did not have Math class that day and Friday was a short day with no academics. Now, I had all week to study for this test but I'm buckling down right now! If i don't get a good grade on this exam I will look foolish and be disappointed! After all, A week to study for a test?!? Along with extra time before this week!?! I have to get a good grade other wise that is just not acceptable!

Let a and b be the legs of a triangle and c be the hypotenuse.


The pythagorean theorem then says that a%5E2%2Bb%5E2=c%5E2


Now say that b is the missing leg, this would then mean that solving for b would give us b=sqrt%28c%5E2-a%5E2%29
