Answer:
Neither parallel nor perpendicular
Step-by-step explanation:
To tell whether two lines are parallel or perpendicular, look at their slopes.
Parallel lines will have the same slope. This isn't the case since the first line has a slope of 1 and the second has a slope of -1.
Perpendicular line have slopes that are negative inverses of the other. This also isn't the case for these two lines. Although the slopes have opposite signs, the numbers aren't inverses.
The two lines are neither parallel nor perpendicular.
Answer: 85 degrees
Step-by-step explanation: 20x+5+24x-1=180
44x+4=180
-4 -4
44x=176
division property of equality x=4
20(4)+5=
80+5= 85 degrees
