A linear pair means the adjacent angles form a line...meaning they equal 180 degrees
Answer:
What do you need help with?
Step-by-step explanation:
The answer is 97, because when you add up 42 and 55 you get 97. Then you subtract that by 180 because a triangles angles add up to 180. 180-97=83. Z=83. Z and y are supplementary to eachother, so therefore 180-83= 97. Supplementary means they add up to 180.
The lines are intersected at point (0, -5). So (0, -5) is the solution.
Answer is the third one
(0,-5 )
