Answer: 167°
Step-by-step explanation:
We know that a pair of angles is said to be supplementary angles if its sum is added up to 180 degrees.
If the measure of an angle is 13°, then the measure of its supplement will be :-
[tex]180^{\circ}-13^{\circ}=167^{\circ}[/tex]
Therefore, if measure of an angle is 13°, then the measure of its supplement will be 167°.
