You withdraw $29.79 from your bank account. now your balance is −$20.51. write and solve an equation to fi nd the amount of money in your bank account before you withdrew the money.

-$20.51+$29.75=x

x=original cost

9.24= x if you need it

(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

the answer is two. hope this !
