Could you guys on every question because i really don't understand. also answer this right now because i need the answers right. pleassse

(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

answer: 8d

step-by-step explanation:

45+5= 50+5=55+5=60

it would rotate about 180 degrees.
