good work so far. Now just solve the equations.
Plug in the expressions for A and B, and you can then solve for C.
Then work back to evaluate A and B, using the value of C.
In triangle ABC,if m∠A is thirteen less than m∠C and m∠B is eleven less than four times m∠C, find the measurement of each angle.
A+B+C= 180
A= 13-C
B= 4C-11

This did not help. I tried this and the ending up result did not end up to be 180
Shouldn't it be C-13 instead?
it says 13 LESS THAN not C is less than
