Recall that complementary angles are two angles whose measures add up to 90 degrees.
Let the measure of the given angle be \$84^\circ\( and the measure of its complementary angle be \)x$ degrees.
Set up the equation based on the definition of complementary angles: \$84 + x = 90$.
Solve for \(x\) by subtracting 84 from both sides: \(x = 90 - 84\).
Simplify the expression to find the measure of the complementary angle.
