Enter your answer, in simplified form, in the box

68-b

Step-by-step explanation:

(66+6)-(b+4)

72-b-4

72-4-b

68-b

(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

6 and 24

step-by-step explanation:

6 x 4 = 24
