Algebra.Com's Answer #102829 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! The measure of the vertex angle of an isosceles triangle is 126. Find the measure of each base angle. \n" ); document.write( "Draw the picture of an isosceles triangle. \n" ); document.write( "Let the vertex angle be 126 degrees \n" ); document.write( "That leasve 180-126 = 54 degrees for the other two angles combined. \n" ); document.write( "Each of them must be 54/2 = 27 degrees \n" ); document.write( "--------------------------------- \n" ); document.write( "Also, \n" ); document.write( "If the measure of an exterior angle drawn at vertex M of triangle LMN is x, then m angle L + m angle N is what? \n" ); document.write( "Draw a triangle. \n" ); document.write( "Draw an exterior angle; it is the supplement of the interior angle where you \n" ); document.write( "drew it. The measure of the exterior angle is x; its supplement is 180-x \n" ); document.write( "------- \n" ); document.write( "Then the measure of the sum of the other two angles is 180-[(180-x)] = x \n" ); document.write( "------------ \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " \n" ); document.write( " |
