is complementary 90%?
Sorry, but this is not a proper question. Try again. Be clearer about what it is that you want to know.
is a complementary event 90% or 180%?
Chris: two angles (not just one) are called "complementary" if they add up to 90 degrees. 30 and 60 are complementary because ... ? two angles are "supplementary" if they add up to 180 degrees. 120 and 59 degrees are ... ?
if 2 angles of a quadrilateral measure 90 degrees and the third angle measures 125 degrees what does the fourth angle measure?
I don't see right off, Chris, where "complementary" and/or "supplementary" belong in this question. Are you discussing a new question or one that you posted previously?
You're asking about a polygon (specifically, a "quadrilateral," or a figure with four sides). My interpretation of this question is that two different angles of this quadrilateral are 90 degrees (each). Those angles, as well as the 125 degree angle, are called "interior angles" of the quadrilateral. Would you please Google this: "interior angles of a polygon." doing so will provide you with info on how to determine the sum of the interior angles of a polygon with any number of sides. For a quadrilateral, that would be four sides, right?
