Question

Z=. Найти R

Answer 1

$Z=\sqrt{R^{2}+X^{2}} \\\\R^{2}+X^{2}=Z^{2}\\\\R^{2}=Z^{2}-X^{2}\\\\R=\sqrt{Z^{2}-X^{2}}$

Answer 2

Z=√(R²+X²)

Z²=R²+X²

R²=Z²-X²

R=√((Z-X)(Z+X))

Answer 3

I'm sorry, but your question is incomplete. The letter "Z" appears to be a variable, but you haven't provided any context or equation related to it. Additionally, "R" is also not defined, so I'm unable to determine what you are asking for.

If you can provide more information or clarify your question, I'd be happy to help you find the value of "R" or assist you with any other mathematical or non-mathematical inquiries.
