The degree measure of one of two complementary angles is 30 less than twice that of the other. What are the degree measures of t
he angles? (Remember that complimentary angles add to be 90 degrees) 45 degrees and 45 degrees 30 degrees and 60 degrees 27 degrees and 63 degrees 40 degrees and 50 degrees
n+ 2n -30 =90⁰ (because they are complementary) Combine like terms -- 3n -30 = 90 Add 30 to both sides of the equation 3n=120° Divide both sides by 3 and n=40° 2n -30 = 80 -30 = 50° So one angle is 40° and the other is 50° and those angles are complementary.
