Question

An angle measures 42. what is the measure of its complementary angle and supplementary angle, in that order ?

Answer 1

in the complementary angle, the sum of the angle is 90 degree

and in the supplementary angle, the sum of the angle is 180 degree

for complementary angle

42 + x = 90

x = 90 - 42

x = 48

so 48 is the complementary angle

for supplementary angle

42 + x = 180

x = 180 - 42

x = 138

so the supplementary angle is 138 .
