Answer:

$b=135\\c=45$

Step-by-step 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!
