The answer is c. y=x-2 i believe
The answer is 7.5 liters that should of evaporated
So if your solution -6(0.75)x=4(x-1)^2 is the answer
So you would use SOH CAH TOA and the inverse of whatever we will use to solve this problem. so we have two measurments 40ft and 25ft. so we will use the inverse of SOH which is sin. so Sin^-1(25/40)=38 degrees is your answer.
