180 = 90 + 2x

90 = 2x

x= 45

Angles on a straight line add up to 180. So to work out a :

180 = 45 + a

135 = a

Determine whether the graphs of y=-9x+11 and y=1/3x-12 are parallel, perpendicular, coincident, or none of these.

nirvana33 [79]

Answer:

None

Step-by-step explanation:

Parallel means exactly the same just lower or higher(same slope)

Coincident means directly on top of one another which they are not

Since it is none of these than the answer is obviously none of these ;)

I hope this helps u pls give a brainliest and a thx :)
