Algebra.Com's Answer #368192 by KMST(5328)![]() ![]() You can put this solution on YOUR website! I agree with A+B+C=180 and B=3A \n" ); document.write( "However the translation for \"The measure of angle C is 20 degrees more than that of angle A\" is C=A+20 \n" ); document.write( "You get the system of equations \n" ); document.write( " \n" ); document.write( "Substituting the expressions for B and C from the second and third equations into the first equation, you get \n" ); document.write( " \n" ); document.write( "Now you can substitute the value found for A in the last two equations to find B and C \n" ); document.write( " \n" ); document.write( " |
