much money did he make by selling the bicycle and helmet to Jin?
Stefan originally spent $

168

Step-by-step explanation:

Stefan sells Jin a bicycle for $150 and a helmet for $18. The total cost for Jin is 140% of what

Stefan spent originally to buy the bike and helmet. How much did Stefan spend originally? How

much money did he make by selling the bicycle and helmet to Jin?

Stefan originally spent $ because you said "Stefan spent originally to buy the bike and helmet" so the answer would be 168

(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
