Recall that two angles are complementary if the sum of their measures is \(90^\circ\).
Given one angle measures \(3^\circ\), let the complementary angle be \(x^\circ\).
Set up the equation for complementary angles: \(3^\circ + x^\circ = 90^\circ\).
Solve for \(x\) by subtracting \(3^\circ\) from both sides: \(x = 90^\circ - 3^\circ\).
Calculate \(x\) to find the measure of the complementary angle.
