Answer: A: 2 and C: 4
Step-by-step explanation:
supplementary angles form a straight line adding up to 180 degree angles
It's b because you have to round up
Answer:
105
Step-by-step explanation:
l is parallel m so angle 3+angle 6=180
To check if this point lies on the line, plug in a 2 for x and a y for 1 and solve
x+2y=5
2+2(1)=5
4=5
Since this statement isn't true, then the point doesn't lie on the line
Hope this helps
