Answer:
b = 2
c = -1
d = -2

If two angles are complementary, then it they add up to 90 degrees.
<span>If they add up to 90 degrees, then they are right angles </span>
<span>So, If two angles are complementary, then they are right angles </span>
<span>Converse: If two angles add up to 90 degrees, then they are complementary. T </span>
<span>Inverse: If two angles are not complementary, then they do not add up to 90 degrees T </span>
<span>Contrapositive: If two angles do not add up to 90 degrees, then they are not complementary angles T </span>
<span>Hope this helps! ;D</span>
