Explanation Given: The dimensions of the triangle KLM as M = 31 ° and k = 27 ft . Procedure used: “Use the cosine function to find unknown parts of a right triangle. 1. Two of these three parts of a right triangle must be known: (a) One acute angle. (b) The side opposite the known acute angle. (c) Hypotenuse 2. Substitute the two known values in the ratio cos θ = adj hyp . 3. Solve for the unknown part.” Calculation: From the given figure, observe that m is the opposite side; l is the hypotenuse and k is the adjacent side with respect to M

5) You are purchasing a game for $30. You have a 5% off coupon and sales tax is 5%. What will your final price be? Does it matter if you take off the coupon first or add in the tax first? 6) You have ten coupons that allow you to take 10% off the sales price of a jacket, and for some strange reason, the store is going to allow you to use all ten coupons! Does this mean you get the jacket for free? Let's really think about what would happen at the checkout. First, the teller would scan the price tag on the jacket, and the computer would show the price is $100. After the teller scans the first coupon, the computer will take 10% off of $100, and show the price is $90. (Right? Think about why this is.) Then after the teller scans the second coupon, the computer will take 10% off of $90. (a) Continue this reasoning to fill in the table below showing the price of the jacket (y) after you apply x coupons. (b) Make a graph showing the price of the jacket from x = 0 to x = 10 coupons applied.…
