Question

One angle is equal to 30° Find its supplementary angle​

Answer 1

Answer

The supplement of an angle is 180 degrees minus the angle.

If your angle is 30 degrees, then its complement is 60 degrees because 60 + 30 = 90.

If your angle is 30 degrees, then its supplement is 150 degrees because 30 + 150 = 180.

All the best :)
