Line a intersects line b, forming angles of 135 degrees and 45 degrees. A third line,line c, is perpendicular to line a and forms triangle ABC. What is the measure of the angle between lines b and c?
a. 35 degrees
b. 45 degrees
c. 90 degrees
d. 135 degrees
e. Can't be determined
Can you show me how the lines are drawn out?

sorry  no pictures here.
Surely you can draw a reasonable picture of lines a and b.
Let a be the xaxis
Then b is the line y=x (45°)
Now, line c will be parallel to the yaxis.
So, you now have a right triangle with two 45° angles.
