find the measures of 2 supplementary angles if one angle is 12 more than 3 times the other find the measures of 2 supplementary angles if one angle is 12 more than 3 times the other @Mathematics

Answer 1

the first supplementary angle is 42 degrees and the second is 138 degrees

Answer 2

supplementary angles just mean that the angles add up to 180 degrees; in order to solve the equation, you've got to set the two angles up to 180.

Answer 3

with 180=3x=120=x?

Answer 4

*180=3x+12)=x

Answer 5

how did you get it?
