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.
Okay first off. You want to combine like terms.
2.75-1.5=1.25j
2.25+3=5.25
Now you just fit those two answers into the final answer and you have:
1.25j+5.25.
