Adds up to 180 degrees. For two angles to be non-supplementary the must sum to anything other than 180 degrees, to be non-adjacent they can't share a common side (Ray)
True
∠2 and ∠5 are both vertical at the vertex of the 2 straight lines
Answer:
A
Step-by-step explanation:
To write the equation of the line. first calculate the slope using the slope formula.

Since the slope of this line is 0, it is horizontal and has the form y=b where b is the y-coordinate. So y = 2 is the equation. In general form, it would be y-2 = 0
