Answer:
I think A
Step-by-step explanation:
With the equasions shown A makes the most sense
Table C since it is decreasing at a constant rate of 5.
55 - 5 = 50
50 - 5 = 45
45 - 5 = 40
The answer is 132. 132 is the original price. 80$ x 65% = 52. 80 + 52 = 132. So 132 is answer and original price.
Assuming that c is the length of AB (as is usually the case in the angle-side notation for triangles):
If sin(35) = 12/c, we can transform by multiplying both sides by c, and dividing both by sin(35) to get
c = 12/sin(35)
Evaluating using a calculator gives 20.92 units.
