What are the possible measures of an angle that is complementary to a 72° angle?
A.8°
B.18°
C.72°
D.108°
To find the measure of an angle that is complementary to a given angle, we need to remember that complementary angles add up to 90 degrees.
So, to find the complementary angle to a 72° angle, we subtract 72° from 90°:
90° - 72° = 18°
Therefore, the possible measure of an angle that is complementary to a 72° angle is 18°.
Hence, the correct answer is B. 18°.
To find the complementary angle to a given angle, you need to subtract the given angle from 90°.
In this case, the complementary angle to a 72° angle would be:
90° - 72° = 18°
So, the possible measure of an angle that is complementary to a 72° angle is 18°.
Therefore, the correct answer is B. 18°.
