What are the coordinates of a’ in quadrilateral a’b’c’d’

cordanite a is (-1,2)

The coordinates of A is (-1, 2)

You just first move over to the left on the X axis making your x coordinate a negative. So when you you get to -1 you go up to where A is, which is at positive 2. Your y coordinate is positive because you're moving up on the Y axis and not down.

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
