E, A, F
Step-by-step explanation:
The "system" of equations can't be solved for (x, y), because there's no "system" of equations given. There's really only one equation.
Either of these two equations can be massaged to look exactly like the other one. And if you graph both equations, you find that they're both the same line on the graph.
ANY point on the line is a solution to both equations ... and we all know how many different points there are on a line.
Answer: A is the right angle
Step-by-step explanation:

400 + 225 = 625
625 = 625
hope this helps :)
