Solve each system of equations by using any method. Two angles are supplementary. The measure of one of these angles is 12^∘ less than one third of the measure of the other. What is the measure of each angle?
Added by Tommy O.
Step 1
From the problem, we know that: x + y = 180 (because the angles are supplementary) and x = (1/3)y - 12 (because one angle is 12 degrees less than one third of the other) Now we can substitute the second equation into the first equation: (1/3)y - 12 + y Show more…
