Question 639289
1. Never. (Complements are 90 degree angles, and obtuse angles are over 90 degrees as it is.)
<p>2. Sometimes. (Any angle can sometimes have a supplement, sure.)
<p>3. Always. (Supplementary angles are 180 degrees, so to go from one angle under 90 degrees, you need another angle that is over 90 degrees.)
<p>Hope this helps!
