Angle of elevation= 61°
Height of Sarah =h = 5.5ft
Distance(from base of statue) between Sarah and statue = 166 ft
Now,
tan(61°)= H/166
H= 299.47 ft
but in the height H you also add the height of of Sarah then you get the height of statue.
Height of statue of the liberty = H+h
= 299.47+5.5
= 304.97 ft
