How do I show work for this question

The angle is a 90 degree angle, which is seperated into two angles. One of the angle measures is 63 degrees, and the other one is represented as an unknown variable (b). Since the whole thing is 90 degrees, you subtract 90 by 63, to get the remainder, 27. 27 = b. The measure of angle b is 27 degrees.

(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
