Algebra.Com's Answer #26980 by gsmani_iyer(201)![]() ![]() You can put this solution on YOUR website! \n" ); document.write( "The sum of the angles in a triangle is equal to 180 degrees. The angles opposite to the equal sides are equal. \n" ); document.write( " \n" ); document.write( " The top angle = 72 degrees. \n" ); document.write( " \n" ); document.write( " The sum of the other two angles = 180-72 = 108 degrees. \n" ); document.write( " \n" ); document.write( " Since both the angles are equal (Opp to sides of 15 cms), their angles are \n" ); document.write( " \n" ); document.write( " = 108/2 = 54 degrees each.
