Respuesta :
Complementary angles add up to 90 degrees.
If you know one angle subtract that from 90 to find the other angle.
Supplementary angles add up to 180 degrees.
If you know one angle, subtract that from 180 to find the other angle.
Answer:
Since complementary angles add up to 90 degrees, you subtract the angle that you know, from 90, and you'll get the missing angle.
Since supplementary angles add up to 180 degrees, you subtract the angle that you know, from 90, and you'll get the missing angle.
