On a horizontal number line, -6 is located to the (left) of -4. So, -6 is (less than) 4.
Cosα=x/L
L=x/cosα, we are told that the ladder base is 48 ft from the base of the wall and α=39° so:
L=48/cos39 ft
L≈61.76 ft (to nearest hundredth of a foot)
Subtract to find the amount of tax paid then divide the amount of tax paid by the price of the item bought.
7.61 - 6.95 = 0.66 (amount of tax paid)
0.66/6.95 = 0.0949 x 100 = 9.49 %
Answer: 9.49 % (round off as needed)
