Answer:


b=135\\c=45

Explanation:

The angle that measures 135 degrees and angle b are opposite angles. Opposite angles are congruent. Therefore, angle b=135.


b=135

A straight line has an angle measure of 180 degrees. This means that 135+c would equal 180 degrees.


135+c=180

Subtract both sides by 135


135+c-135=180-135\\c=45

I hope this helps!
