**PsyDAG**, Saturday, April 3, 2010 at 12:30pmA triangle has 180º.

B = 5A

C = 4A - 18º

A + B + C = 180º

Substitute values of B and C in terms of A in the last equation to solve for A. Use that value to get B and C in the other two equations. Check by inserting the three values found into the last equation.
