This is probably most-simply solved by

. . . . .

. . . . .

. . . . .

The above would be the "exact" solution. The "approximate" solution would be found by plugging each of:

. . . . .

...into your calculator, and rounding the outputs to the required three decimal places.

Note: In this particular case, the "exact" solution won't involve square roots. For the "approximate" solutions, you'll have to tack on three (entirely unnecessary) zeroes after the decimal point.
