Check if I rounded this number off correctly? Thank you :)
x^2 = y^2 + 7^2
x^2 = y^2 + 49
x^2 = 7^2 + 49
x^2 = 49 + 49
x^2 = 98
x^2 = √98
x^2 = 7√2
7√2 = 3.2

Best ResponseYou've already chosen the best response.0If x = 3.1463, I would move to the thousandths place. 6 is larger than 5. x = 3.15 Then, I move to the hundredths place. x = 3.2
