Answer:
19.72 ft
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the relation between angles and sides of a right triangle:
Tan = Opposite/Adjacent
Then the relations in the attached drawing are ...
tan(α) = 42/73
tan(α +10.3°) = (42 +SH)/73
Solving the first equation for α, we get ...
α = arctan(42/73)
Solving the second equation for SH, we get ...
73 tan(α +10.3°) = 42 +SH
SH = 73·tan(arctan(42/73) +10.3°) -42 = 73·tan(29.91°+10.3°) -42
SH = 73·0.84547 -42 = 19.720 . . . . feet
The height of the statue is about 19.72 feet.

It seems appropriate to use the linear regression function of your calculator for this. Looking at the data, you know the slope is generally positive, so only the 1st and 3rd choices are potentially viable.
