Answer:
167°
Step-by-step explanation:
The supplement of an angle will always be the measure of an angle, when added to the original, will equal 180°.
If we know the measure of 1 of these angles, we can easily find the measure of the other, assuming x is the missing angle measure.
[tex]13+x=180[/tex]
We can subtract 13 from both sides to get the value of x.
[tex]13+x-13=180-13\\\\x=167[/tex]
Hope this helped!
