:
lets call our angles a and b
:
a=3b-4..........eq 1
a+b=180.........eq 2

The sum of the measures of two supplementary angles is 180 degrees. Let x be the measure of one of your angles, then the other one is 3x - 4. The sum of x and 3x - 4 must equal 180.



Solve for x to get one of your angles, subtract that value from 180 for the other one.
