Straight line = 180 degrees so angle opposite a = 180-128 = 52
then triangle adds up to 180 degrees so a= 180-52-73 =55 degrees

Answer:
We try to resolve the equations in our own to answer the question above.
2x + y = 5
x − 2y = 10
y = 5 − 2x
x − 2(5 − 2x) = 10
x - 10 + 4x = 10
5x - 10 = 10
5x = 20
x = 4
Therefore, the correct answer among the choices is the second option. He did not distribute correctly.
