3 doughnuts and 2 cakes costs £7. 5 doughnuts and 4 cakes costs £13.
Find the cost of a doughnut.
Find the cost of a cake.

cost of the doughnut = 1

cost of the cake =2

(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

your answer is the frist one
