I need some help with solving problem : In triangle ABC the measurement of angle A is 5 degrees more than 3 times the measure of angle B. Angle C measures 20 degrees less than angle B to determine the measurement of angles A,B,C?

\n" ); document.write( "Equations:
\n" ); document.write( "A = 3*B + 5
\n" ); document.write( "C = B-20
\n" ); document.write( "A + B + C = 180
\n" ); document.write( "------------------------
\n" ); document.write( "Substitute for A and C; solve for \"B\"::
\n" ); document.write( "3B+5 + B + B-20 = 180
\n" ); document.write( "5B = 165
\n" ); document.write( "B = 33 Degrees
\n" ); document.write( "A = 3B+5 = 99+5 = 104 Degrees
\n" ); document.write( "C = B-20 = 33-20 = 13 Degrees
