First answer will be marked brainlest

if two angles are complementary angles they can be

a. obtuse angles

b. supplementary angles

c. acute angles

d. linear pairs

Option C: acute angles

Step-by-step explanation:

Option A: Obtuse angles

Obtuse angle is an angle which is more 90° and less than 180°. Complementary angles are angles whose sum is 90°. Hence, Obtuse angles is not a correct answer.

Option B: Supplementary angles

Supplementary angle is an angle whose sum is 180°. Complementary angles are angles whose sum is 90°. Hence, Supplementary angles is not a correct answer.

Option C: Acute angle

Acute angle is an angle which is less than 90°. Complementary angles are angles whose sum is 90°. Hence, Acute angle is the correct answer.

Option D: Linear pairs

Two angles are said to be linear if the sum of two angles is 180°. Complementary angles are angles whose sum is 90°. Hence, Obtuse angles is not a correct answer.

Hence, If two angles are complementary angles they can be acute angles.
