Question

Can someone help me lol

Answer 1

the answer is number C

`{a}^(2) + {b}^(2) = {c}^(2) \\ {b}^(2) = {c}^(2) - {a}^(2) \\ b = \sqrt{ {c }^(2) - {a}^(2) }`

Explanation:

If you need any explanation in it or anything on math you can communicate with me on Whats on this number +201557831028 or in email or face or anything

I can help you solve what you want in mathematics in exchange for some money. If you want to, you can inform me about it and I will help you.

Answer 2

I Think

B. b = sqrt c^2 - a2

Explanation:

1. move the a^2 to the other side

b^2 = c^2 - a^2

2. squareroot

b = sqrt c^2 - a^2
