You didn’t give the question
Just a guess, but the angle inside the triangle that's not x or y is the remaining angle after subtracting the 30 degrees shown. That makes the non labeled angle inside the triangle 150 degrees. since all triangles are 180 degrees, this means x and y add up to 30. They look roughly the same, so i'd guess they're both 15 degrees.
The answer would be d. because you’re moving back then moving downwards starting from 0 (the origin). Which would make x and y negative numbers.
Total area = 2,250 ft + 706.50 ft = 2,956.50 ft. pretty sure that’s the answer.
