Algebra.Com's Answer #363924 by stanbon(75887) ![]() You can put this solution on YOUR website! The smallest angle in a triangle is half of the largest angle. The third angle is 40° less than the largest angle. Find the measure of all three angles. \n" ); document.write( "------ \n" ); document.write( "Let smallest be \"x\". \n" ); document.write( "Then largest is \"2x\". \n" ); document.write( "And 3rd angle = \"2x-40\" \n" ); document.write( "----------------- \n" ); document.write( "Equation: \n" ); document.write( "x + 2x + 2x-40 = 180 \n" ); document.write( "5x = 220 \n" ); document.write( "x = 44 degrees \n" ); document.write( "--- \n" ); document.write( "2x = 88 degrees \n" ); document.write( "--- \n" ); document.write( "2x-40 = 48 degrees \n" ); document.write( "======================== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "======================== \n" ); document.write( " |
