Find the measure of the complement of an angle of measure 70°?

Advertisements

Solution

Let the measure of the complementary angle be x.
70 + x = 90
∴ 70 + x - 70 = 90 - 70
∴ x = 20°
The measure of the complement of an angle of measure 70° is 20°

  Is there an error in this question or solution?
