Answer: 0
Step-by-step explanation:
You can solve for tangent by dividing sin by cos.
Looking at the unit circle, at 0, sin is 1 and cos is 0, so you would simply have 0/1, which equals zero.
Regular price= x times of sale price
26=x times 19.50
divide both sides by 19.50
1.33333333333333333=x
so it is 1.33333 times the sale price or 4/3
