Question

one angle of two supplementary angles is four times the other angles is four times the other angle. find the mesures of the two angles

Answer 1

supplementary angles add up to 180 degrees

a + b = 180
a = 4b

4b + b = 180
5b = 180
b = 180/5
b = 36 <=== here is 1 angle

a = 4b
a = 4(36)
a = 144 <== and here is the other one
