Find the measure of the complement and the supplement of each angle. \(1^{\circ}\)

Draw (or find and describe) an object of genus 4 or more.

Use an algebraic equation to find the measures of the two angles described. Begin by letting \(x\) represent the degree measure of the angle's complement or its supplement. The measure of the angle is \(56^{\circ}\) greater than its complement.

Use an algebraic equation to find the measures of the two angles described. Begin by letting \(x\) represent the degree measure of the angle's complement or its supplement. The measure of the angle is \(81^{\circ}\) more than twice that of its supplement.
