I would believe it to be 22
Answer: AC=12 cm
Step-by-step explanation:
To solve this problem you must apply the law of sines, as you can see below:

Where:
a=13
A=85.2°
B=71.6°
Therefore, you must solve for b, then, you obtain that the lenght AC asked in the problem above is:

Dilation about the origin multiplies every coordinate by the scale factor.
C' = 4(-5, 2) = (-20, 8)
A' = 4(-4, 4) = (-16, 16)
T' = 4(-1, 2) = (-4, 8)
Step-by-step explanation:
8 is more than 2/4 because the answer of 2/4 is 0.5 so 8 is more than 2/4
20% off means you paid only 80% of the original price.
0.8x=40
x=40÷0.8=50
so the original price is 50
