**MathMate**, Wednesday, September 23, 2009 at 9:08pmIt depends on the problem.

If the two orthogonal components (at right angles) are given to 4 significant figures, your answer should do the same.

For example,

x=42.34

y=55.31

z=√(x²+y²)

=(69.65578)

But 69.65578 has 7 significant figures, which is more than the original information, so round to the same number of figures, namely 69.66 would do.
