Answer:
Step-by-step explanation:
if 
I believe the answer is D.
The other answers would not make sense, because we do not know what kind of triangle we are looking at and none of the lines are parallel or perpendicular. Therefore we need two angles. C would not work, because if we knew A or B, we would know that the two angles are supplementary. If we had A, then B is 180-A, and vice versa. We do not need both A and B.
Answer:
2
Step-by-step explanation:
Store A's prices are represented by the expression 15x - 2.
Store B's prices are represented by the expression 3(5x + 7).
To find when the 2 stores charge the same rate , we set the expression equal and solve for x
15x - 2 = 3(5x+7)
15x -2 = 15x + 21
Subtract 15x on both sides
-2 = 21
We cannot solve for x
So , the price of two stores never be same
Two stores never charge the same rate
