In a triangle, the second angle is twice the first and the third angle is 20 drgees less than the first. Find the measure of all three angles.
\n" ); document.write( "LET FIRST ANGLE =A
\n" ); document.write( "SECOND ANGLE = 2*A
\n" ); document.write( "THIRD ANGLE = A-20
\n" ); document.write( "SUM OF ALL 3 ANGLES =A+2A+A-20=180
\n" ); document.write( "4A=180+20=200
\n" ); document.write( "A=200/4=50
\n" ); document.write( "SO THE 3 ANGLES ARE A=50,2*50=100,50-20=30. \n" ); document.write( "

\n" );
