Recall that supplementary angles are two angles whose measures add up to 180 degrees.
Given one angle measures \(1^\circ\), let the supplementary angle be \(x^\circ\).
Set up the equation for supplementary angles: \(1^\circ + x^\circ = 180^\circ\).
Solve for \(x\) by subtracting \(1^\circ\) from both sides: \(x = 180^\circ - 1^\circ\).
Calculate \(x\) to find the measure of the supplementary angle.
