Question

1. Find the measure of an angle which is complement of itself ? 2. Find the measure of an angle which forms a pair of supplementary angles ? 3. An angle is five times its complement, Determine its measure . 4.Write the complement of each of the following angles 1) 20 degree 2) 35 degree 3) 90 degree 4) 77 degree 5) 30 degree

Answer 1

1. The angle be xo Complement of this angle is also xo The sum of the measures of complementary angle pair is 90o Therefore, x + x = 90    x=45
