The third angle is 80° more than the sum of the other two angles. Find the measure of the second angle.\r \n" ); document.write( "\n" ); document.write( "Let x be the first angle above. Then since the three angles need to add up to 180:\r \n" ); document.write( "\n" ); document.write( "x + 4x + (x+4x+80) = 180\r \n" ); document.write( "\n" ); document.write( "Solve for x and the second angle is 4*x. \n" ); document.write( " |
