In a triangle a angle is x degrees ,b angle is 2x degrees ,c angle is 105 degrees then find out the value of x ?\r
\n" ); document.write( "\n" ); document.write( "x + 2x + 105 = 180\r
\n" ); document.write( "\n" ); document.write( "3x + 105 = 180\r
\n" ); document.write( "\n" ); document.write( "Subtract 105 from each side of the equation.\r
\n" ); document.write( "\n" ); document.write( "3x + 105 - 105 = 180 - 105\r
\n" ); document.write( "\n" ); document.write( "3x = 75\r
\n" ); document.write( "\n" ); document.write( "Divide each side by 3\r
\n" ); document.write( "\n" ); document.write( "3x/3 = 75/3\r
\n" ); document.write( "\n" ); document.write( "Answer:\r
\n" ); document.write( "\n" ); document.write( "x = 25 degrees and\r
