Algebra.Com's Answer #245338 by unlockmath(1688)![]() ![]() You can put this solution on YOUR website! Hello, \n" ); document.write( "We can let x represent the second angle. Also we know every triangle has 180 degrees so the equation will look like: \n" ); document.write( "x + 4x + (2x+5) = 180 \n" ); document.write( "Combine like terms and subtract 5 from both sides to get: \n" ); document.write( "7x=175 \n" ); document.write( "Now divide both sides by 7 to result in: \n" ); document.write( "x=25 degrees for the second angle \n" ); document.write( "Other two angles are: 100 and 55 degrees. \n" ); document.write( "Make sense? \n" ); document.write( "RJ \n" ); document.write( "www.math-unlock.comn \n" ); document.write( " \n" ); document.write( " |
