Answer= c
In this case you've got to place the vector from the origin, so you have to get the difference from both points (x2-x1) and (y2-y1)
So you get that the vector from the origin is (18,-7)
Know you know the vector v is three times the vector u, so you multiply three times the vertex, but remember the vector v goes int he opposite direction, so the vector v from origin the the terminal point is (-54, 21)
To find the % sales tax, you simply need to find that percentage of the price.
5% of $98.75 is $4.94
98.75x0.05=4.94
8% of $98.75 is $7.90
98.75x0.08=7.90
6.5% of $98.75 is $6.42
98.75x0.065=6.42
Therefore, of the sale amount $98.75,
5% sales tax is $4.94
8% sales tax is $7.90
6.5% sales tax is $6.42
If you want to find the total price, add the sales tax to the sale price.

Answer:
∠7 = 51°
∠8 = 129°
Step-by-step explanation:
All of the obtuse angles are congruent, as are all of the acute angles. The acute and obtuse angles are supplementary.
∠8 = ∠1 = 129°
∠7 = 180° -129° = 51°
_____
<em>Additional comment</em>
Technically, angles 1 and 8 are called "alternate exterior angles." As such, they are congruent. Angles 7 and 8 form a "linear pair." As such, they are supplementary.
