Use trigonometry to find L.
Tangent = opposite over adjacent on any right triangle.
tan(L) = 18/23
Take the inverse on both sides.
arctan(tan(L)) = arctan(18/23)
L = 38.0470425318
L = 38.05°
Done.

Step-by-step explanation:
The given triangle has coordinates (-3,3),(1,4), and (2,2).
If we dilate with a scale factor of 2 centered at (-3, 1), then we use the rule:
To find the image of (-3,3), we substitute x=-3, and y=3
This implies that: and
This implies that:
Hence the image of (-3,3) is (-3,5)
We repeat the same process to obtain:
We now plot the image points and join the vertices with a straight edge.

Answer:
Costco has the better deal.
Step-by-step explanation:
Find the unit rate for Costco:
<em>Remember, the unit rate is when one of the numbers in a ratio is 1.</em>
<em />
Toilet paper : Price
6 : 4.99
(divide both sides by 6)
1 : .83
<em>Remember to round to the nearest hundredth place because money only goes two places after the decimal point.</em>
<em />
Therefore, 1 roll of toilet paper at Costco costs 83 cents.
Find the unit rate for Target:
Toilet paper : Price
8 : 6.99
(divide both sides by 8)
1 : .87
Therefore, 1 roll of toilet paper at Target costs 87 cents.
Conclusion:
.83 < .87
In conclusion, Costco has a better deal because toilet paper is cheaper per roll.
