Question

anonymous · Answer

Is your triangle a right triangle?

anonymous · Answer

heres a picture of what I was given
and the whole question was... TV = 20 and CU = 12. Find the length of UV. Show equations and all work that leads to your answer. I just guessed base was 10 and height was 12

anonymous · Answer

Use Pythagoras's theorem from here: 
$$a ^{2}+b ^{2}=c ^{2}$$ where TU is your hypotenuse

anonymous · Answer

that cant be right a2+b2=c2 would look like 10squared which is 100 and 12squared which is 144 it says add them together which is 59,536 theirs no way that's right

anonymous · Answer

If we added 100 to 144, we'd get 244.  So,
$$c ^{2} = 244$$ what is c?

anonymous · Answer

sorry once you square that though you get 59,536

anonymous · Answer

Ahhhhh I see what happened now.  Easy fix we just need to square root the 244 not square it.  So, what the square root of 244
$$\sqrt{244} = ?$$
