Algebra.Com's Answer #358877 by mathstutor494(120)![]() ![]() You can put this solution on YOUR website! Let one angle be x \n" ); document.write( "So second angle = x-45 \n" ); document.write( "and third angle = x/3\r \n" ); document.write( "\n" ); document.write( "As sum of all the 3 angles add up to 180 deg \n" ); document.write( "Therefore x+(x-45)+(x/3) = 180\r \n" ); document.write( "\n" ); document.write( "> x = 96.42\r \n" ); document.write( "\n" ); document.write( "Ans : Angle of the triangles are 96.42, 51.42 and 32.14 \n" ); document.write( " \n" ); document.write( " |
