reflex angle
a = a b = 4a c = 5a-9 a+4a+5a-9 = 180 10a = 189 a = 18.9 degrees
Because the 3 angles in a right angle triangle add up to 180 degrees and if an obtuse angle was included then they would add up to over 189 degrees.
189, for one.

There are several, but here are four: 108, 117, 189, 198.
