The measures of some angles are given below. Write the measures of their complementary angles.45°
✓
Answer
Let the measure of the complementary angle be x°. ∴ 45 + x = 90 ∴ 45+x-45 = 90-45 ….(Subtracting 45 from both sides) ∴ x = 45 ∴ The measure of the complement of an angle of measure 45° is 45°.
