Answer:
a
Step-by-step explanation:
The opposite sides and opposite angles are congruent, thus
5x - 5 = 3x + 25 ( subtract 3x from both sides )
2x - 5 = 25 ( add 5 to both sides )
2x = 30 ( divide both sides by 2 )
x = 15
and
3y - 4 = 2y + 8 ( subtract 2y from both sides )
y - 4 = 8 ( add 4 to both sides )
y = 12
