you can also use some of those online calculators that calculates z-scores. That is probably more accurate than tables. Google 'z-score calculators.'

Or

Distribution Tables
The left hand numbers (bold ones) are the z scores, and the right hand numbers are the area to the left of the particular point. So I found the area and matched it with the z-score.

Notice that $\displaystyle 0.43 - 0.15 = 0.28 $ which is the the difference between the z-scores $\displaystyle 1.5 $ and $\displaystyle 0.4 $ in the table. So its not exact, but close enough.
