Question

Given: If two angles are complementary, then both angles measure less than 90°. Angles that measure less than 90° are acute. ∠1 and ∠2 are complementary. What conclusion can be drawn?

A Only ∠1 is acute.
B Only ∠2 is acute.
C Both angles are acute. D Neither angle is acute.

Answer 1

C. Both angles are acute.

Explanation:

Acute means less than or equal to. So 90° is an acute angle. Complementary angles means boths angles sum up to form 90°. Angle 1 & 2 must be lesser than 90° in order to form a complementary angles.
