Answer:
-0.2
Step-by-step explanation:
Simplifying
5x = 3y + -4
Reorder the terms:
5x = -4 + 3y
Solving
5x = -4 + 3y
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Divide each side by '5'.
x = -0.8 + 0.6y
Simplifying
x = -0.8 + 0.6y
The answer is C, because the angle is obtuse, but also not as big as 160°
