Answer:
30°
Step-by-step explanation:
supplementary angles are two sets of angles whose sum form 180°
According to the problem, one set equals 5 times the other.
Let the other be x,
It means it's compliment is 5x;
It means therefore that ;
x + 5x = 180°
6x = 180°;
x = 180°/ 6 = 30°;
Therefore the angle measures 30° and it's supplement 150°.
