Question

Find m∠1 if ∠1 is complementary to ∠2, ∠2 is supplementary to ∠3, and m∠3 =126

Answer 1

angle 1 is complementary to angle 2: they sum to 90

angle 2 is supplementary to angle 3: they sum to 180

angle 3 = 126

angle 2 = 180-126 = 54 degrees

angle 1 = 90-54 = 36 degrees

angles 1,2 and 3 = 36, 54 and 126

Answer 2
