Answer:
42 and 138
Step-by-step explanation:
Supplementary angle mean that the sum of both angle will be 180 degrees. If the angle is X and Y the equation will be:
x + y = 180
x= 180-y
If three times the measure of one angle(X) is 12 degrees less than the measure of the other(Y), the equation will be
3x= y-12
If you insert first equation to second equation, you can find out:
3x= y-12
3(180-y)= y-12
540-3y= y-12
540+12= y+3y
552= 4y
y= 138
x=180- y
x= 180-138
x= 42
