Algebra.Com's Answer #670937 by josgarithmetic(39630) ![]() You can put this solution on YOUR website! Key is The isosceles triangle ABE. Side AB is congruent to side BE. The angle at B, on interior, is 90+60=150 degrees.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Upper interior angle at A is 60 degrees, but let this be the sum of your x plus y. \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Now back to the isosceles triangle ABE. The TWO base angles each are of measure y. \n" ); document.write( "You already know the 150 degrees at B. \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Now ready to find x. \n" ); document.write( "Again, because equilateral, same as equiangular triangle, \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " |
