Q. The measure of an angle is 21∘21^\circ. What is the measure of its complementary angle? \newline_______∘\_\_\_\_\_\_\_^\circ
  1. Understand Complementary Angles: Understand the sum of complementary angles. Complementary angles add up to 90∘90^\circ. Calculation: 90∘90^\circ (total for complementary angles).
  2. Calculate Total: Subtract the given angle from 90°90° to find its complementary angle.\newlineCalculation: 90°−21°=69°90° - 21° = 69°.
