Answer:
m∠b=20°
m∠c=160°
Step-by-step explanation:
∠c and the 160° angle are vertical, so they are congruent.
m∠c=160°
∠c and ∠b are supplementary, so their sum is 180°.


So, m∠b=20°.
We know the full protractor measures 180 degrees.
We need to know what angle it is on. By looking at it, it looks like it is on 135.
180-135= 45
The angle is 45 <em>degrees.
I hope this helps!
