im doing angles and such...how can you find the measurements of all angles when you only know one measurement? for example:
angle BOA=100 degrees
now how would i find the other angle's measurements? i know about supplementary but is there a trick to use or a key??

  1. That all depends upon what kind of "other angles" you are talking about. Complementary? supplemetary? internal? external? Right triangle angles?
