When full, a 22-gallon gas tank holds 129.8 pounds of gasoline. estimate the weight of one gallon of gasoline. if it costs $91.30 to fill the gas tank, estimate the cost per gallon.

you are saying it as if a fact, not a question, but yes, you would be correct? ; )

step-by-step explanation:

(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
