Could you please explain this : 
If the given statement and conjecture are false, find a counterexample to show this. 
Given: two angles each measure less than 90 degrees.
Conjecture: The angles are complementary. 
A. The statement and conjecture are true
b. <A=40 degree and < B = 50 degrees 
C) < A= 20 degrees and b< 55 degrees
d) <a = 23 degrees and < b = 67 degrees.

When you say "The angles are complementary", that means (by definition) that they must add to 90 degrees.

Is it possible to have 2 angles less than 90 degrees, but not have them add up to 90 degrees?
