phi · Answer

what formula do you use for these problems ?

anonymous · Answer

This would be the Pythagorean Theorem.

anonymous · Answer

We are going to need to use this to answer your question. I think that the answer would be 2.

anonymous · Answer

I think that it's supposed to be c^2-b^2=a^2. 

2.1*2.1=4.41      2.9*2.9=8.41     8.41-4.41=4. 
Can anybody tell me if I did this correctly or not.

anonymous · Answer

I did the sq. rt. of 4, which was 2. You know that the answer cannot be 4 because a cannot be longer then c.

anonymous · Answer

So I am pretty sure that the answer is 2. That is my final answer.

anonymous · Answer

thank you so much! i havent gotten taught this and im in online school so its kindof hard for me to teach myself things. i appreciate it greeeeeeeeeeeatlyyy! :)

anonymous · Answer

It's no problem. Just remember the formula for the Pythagorean Theorem. 

a^2+b^2=c^2, you just have to change this formula accordingly like I did with problem number 2.
