Ethan says that the value of 40.7 is 10 times the value of 40.7 is be correct?

No.

Step-by-step explanation:

40.7 times 10 would be 407, not 40.7 ; 40.7 times 1 is 40.7

(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

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.
