A motorboat is being pulled into a seawall dock by
an electric pulley at a dock that is 8 feet above the
deck of the boat. Let O be the angle of elevation
from the boat to the pulley and let s be the length
of the rope from the pulley to the boat.
Find o when s = 30 feet.

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
