-Multiply
and
to get

So, now you have found the answer.
ACUTE ANGLE.
this is because the angle is less than 90 degree and greater than 0 degree
Answer:
You can use Gaussian Elimination.
Double both sides of the first equation and add the second equation.
6x + 4y = 8
5x - 4y = 3
---------------
11x = 11
x = 1
5 - 4y = 3
-4y = -2
y = 1/2
