Recall that complementary angles are two angles whose measures add up to 90 degrees.
Given that angle \( b \) measures \( 60^\circ \), set up the equation for the complementary angle \( x \) as \( b + x = 90^\circ \).
Substitute the known value of \( b \) into the equation: \( 60^\circ + x = 90^\circ \).
Solve for \( x \) by subtracting \( 60^\circ \) from both sides: \( x = 90^\circ - 60^\circ \).
Simplify the right side to find the measure of the complementary angle.
