Step-by-step explanation:
First Supplementary angle
is the sum of two angles equals to 180degrees
is known as supplementary angles
so now we add one one term and let's check whether it is a supplementary angle or not
a)38° + 52° = 90° and it is not equal to 180°
b)115° +65° = 180°
c)69° +81° =150° and it is not equal to 180°
d)173° + 187° = 360° and it is not equal to 180°
So here only the second pair is a supplementary angle
