It appears that answer choices A and D are identical, as arer B and C.  You might want to verify that you've copied down the answer correctly.

Answers A and D (identical) are the best choices here, due to less rounding off.

(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

3/5
