Problem 15: The answer is choice A
cos(angle) = adjacent/hypotenuse
cos(B) = BC/AB
cos(B) = 12/13
Both of the first two choices represent the amount Connor paid.
15% = 0.15, so when you subtract 15% of d from d, you get the 2nd expression. When you simplify that, you get the 1st expression.
The correct choices are ...
• 0.85d
• d - 0.15d
Answer: 0.2
