For large parties at a seafood restaurant, a tip of 18% is automatically included on the bill. Jerome’s family went out for his
grandmother’s 75th birthday. Their bill came to $268.21 before tip. Calculate the amount of tip that will be charged and the total amount after tip. Round to the nearest cent if necessary .
remember SOH CAH TOA. Sin = opposite/hypotenuse, cos = adjacent/hypotenuse, tan = opposite/adjacent. So in this case use CAH for cos L. Adjacent to L is b, and the hypotenuse is h. Therefore the answer is b/h.
