Answer: 6
Step-by-step explanation:
We know that the tens digit must be 5 or less, so we only need to look at the first 2 rows.
Obviously, anything with a tens digit of 4 will be less.
And for the numbers with a tens digit of 5, since all the one's digits are less than 9, we have 3+3=6 snowmen less than 59 inches in height.
