Not sure the type of answer you are looking for. Yet 270 degrees is 3/4 of a full turn. (90 x 3)
Therefore you could state 3/4 of a turn. Also, 1/4 of a clockwise turn would work.
Answer: =6xy+x..............
4y^2 + 16y
You distribute the 2y into the 2y+8
Let the measure of the angle be x and from that the measure of its complement is 90 - x. The equation that best represent the given condition above is,
3x = (90 - x) - 14
The value of x from the equation above is 19. Thus, the answer is letter A.
