the measure of one angle of a triangle is three times the measure of a second angle. the measure of the third angle is 12 less than the sum of the other two. what are the measures of the 3 angles?

Let the angles be A, B and C

 

We have three equations connecting them:

 

A+B+C = 180

A = 3B

C = A+B-12

 

(I'm assuming the 12 is degrees not radians).

 

Can you take it from here?
