Answer:
B
Step-by-step explanation:
(Standard form is automatically in integers)
Multiply by 3 to take out the fraction
3y=2x+21
-2x -2x
-2x+3y=21
Standard form means Ax+By=C with positive A (usually--some people allow A to be negative).
Multiply by (-1)
2x-3y=-21
(Technically, that's the more correct answer, but since you don't have that choices, it's just the previous one.)
Since all sides of the triangle are equal to that of the other triangle, they must be congruent by SSS. this means the angles are the same, so
A
