Algebra.Com's Answer #380135 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! the second angle is a triangle is one and a half times the measure of the first. the third is 15 degree more than half the first angle. find the measure of each angles in the triangle \n" ); document.write( "------ \n" ); document.write( "Let 1st be \"x\" \n" ); document.write( "Then 2nd is 1.5x \n" ); document.write( "And 3rd (x/2)+15 \n" ); document.write( "------------------------ \n" ); document.write( "Equation: \n" ); document.write( "x + 1.5x + (x/2) + 15 = 180 \n" ); document.write( "---- \n" ); document.write( "2x + 3x + x = 360-30 \n" ); document.write( "6x = 330 \n" ); document.write( "x = 55 \n" ); document.write( "1st = x = 55 degrees \n" ); document.write( "2nd = 82.5 degrees \n" ); document.write( "3rd = 42.5 degrees \n" ); document.write( "======================= \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "============================= \n" ); document.write( " |
