# What is the complement and supplement of 59°?

The complement is ${31}^{\circ}$. The supplement is ${121}^{\circ}$.
The complement of an angle is the remaining angle left up to ${90}^{\circ}$. The supplement is the same idea except with ${180}^{\circ}$.
To find the complement, $90 - 59 = {31}^{\circ}$
To find the supplement, $180 - 59 = {121}^{\circ}$
