For a given value c, the left tail probability table above gives the probability P(z < c). This is the same as P(z <= c), so the table can be used in either situation.

The numbers in the first column represent a standard score to one decimal place. The numbers in the top row represent the second decimal place. To find P(z < -1.45), go down the left column to -1.4 and across until you are under the column labeled 0.05. The corresponding table entry is 0.0735.
