I have a question that ends up saying
And oddly enough, I can't figure out how to solve it. The answer to the question should be 5.09ish. But the only solutions I can think up only end with a bigger or smaller number. Pulling out the 5 gets me

Could someone help me figure out how to do this?
To learn how to work with radicals, try here.r=sqrt(5^2+1)
