$\Large \operatorname{Use}~a^2+b^2=c^2$

anonymous · Answer

ok, and for questions 2-9 can show me how to do one, I did them and the teacher told me I was wrong

geerky42 · Answer

You can rearrange that formula so you can plug in values and find the answer:
For a: $a^2 + b^2 = c^2 \ a^2 = c^2 - b^2\a = \sqrt{c^2-b^2}$
For b, same way as a, so $b = \sqrt{c^2-a^2}$
For c, take square root of both sides: $\sqrt{a^2+b^2}=c$

is that clear?

anonymous · Answer

yes, I do the same the for the word problems to put the formula in

ok so what's answer for number 2?

anonymous · Answer

is it 33 since you have to do
