Algebra.Com's Answer #51187 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! The first angle of a triangle is three times the measure of the third angle. The second angle is five less that the third angle. Find the measure of each angle. \n" ); document.write( "------- \n" ); document.write( "Let the measure of third angle be \"x\". \n" ); document.write( "Then measure of first angle is \"3x\". \n" ); document.write( "And measure of second angle is \"x-5\" \n" ); document.write( "--------- \n" ); document.write( "EQUATION: \n" ); document.write( "1st + 2nd + 3rd = 180 \n" ); document.write( "3x + x-5 + x = 180 \n" ); document.write( "5x=185 \n" ); document.write( "x=37 degrees (measure of 3rd angle) \n" ); document.write( "x-5=32 degrees (measure of 2nd angle) \n" ); document.write( "3x= 111 degrees (measure of 1s angle) \n" ); document.write( "----------- \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
