# Angles L and M are complementary. If the measurement of angle L is 16 degrees, what is the measurement of angle M?

74°.
By definition, complementary angles sum up to 90°. So, if an angle $L$ measures 16°, its complementary $M$ must be such that $L + M = 90$, which means $16 + M = 90$. Solving for $M$, we have
$M = 90 - 16 = 74$
