Answer: The true cost of the jacket is $27 dollars.
Step-by-step explanation: To find the cost of the jacket after the discount just do 30 X .1 to get 3. Then take 3 and subtract it from 30. The mistake the clerk made was he probably just saw 10% and did 30-10=20. The clerk might have brain damage because this is like 5th grade math.

ehh
Answer:
A(-4,4) B(-4,6) C(2,4)
Step-by-step explanation:
Here to write coordinate you have to know abscissa and ordinate.
Abscissa is perpendicular distance of point from Y axis.
Ordinate is perpendicular distance of point from X axis.
Use the Law of Sines (sina/A=sinb/B=sinc/C for any triangle)
YZ/sin30=50/sin90
YZ=50sin30 (sin90=1 :P)
YZ=25m
Use the 30,60,90° triangle ratios 1, √3, 2
YZ/1=50/2
YZ=25m
Using the Pythagorean Theorem....
(2*25)^2=YZ^2+(√3*YZ)^2
2500=YZ^2+3YZ^2
2500=4YZ^2
625=YZ^2
25m=YZ
Sorry I don’t get this one anymore ???
