Question

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

Let one angle be x.
The other angle is 12 + 3x.

Since they are supplementary,

12 + 3x + x = 180

12 + 4x = 180

4x = 180 -12

x = 168 / 4

x = 42

Hence the two angles are 42 degrees and (180 - 42) = 138 degrees.
