B)
20-5= (cx ( -5
C
2-3 = 4+k- j - j+j
3x + 2y = x * XXX) + (yxy
E
3- 20 = 2x3x3 - 6-b).

answer: i can’t tell you that

step-by-step explanation:

(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

5050

hope this !
