Question

find the complement of the following angle 10 dagree

Answer 1

80 degrees. Complementary angles sum up to 90 degrees. So to find the complement of an angle subtract it from 90 degrees.

Answer 2

pair of angles whose sum is 90 degree. Then both the angles are called as complimentary angles
then,
      x degree + 10 dgree = 90 degree
      x degree = 90 degree - 10 degree
      x = 80 degree
