Algebra.Com's Answer #352273 by april4869(19)![]() ![]() You can put this solution on YOUR website! The angles of a triangle equal 180 degrees. The ratio is 2:3:4, so we must find what the 'multiplier' will be to determine the angles measurement.\r \n" ); document.write( "\n" ); document.write( "We have three numbers 2, 3, and 4 all equaling to 180 degrees. \n" ); document.write( "Let x represent your multiplier. \n" ); document.write( "2x+3x+4x=180 \n" ); document.write( "9x=180 \n" ); document.write( "x=20\r \n" ); document.write( "\n" ); document.write( "Now replace x---- \n" ); document.write( "2(20)=40(first angle) \n" ); document.write( "3(20)=60(second angle) \n" ); document.write( "4(20)=80(third angle)\r \n" ); document.write( "\n" ); document.write( "And as you can see all three angles equal 180 degrees. Hope this helps:) \n" ); document.write( " |
