In isosceles triangle CDE, angle C is thirty-nine degrees more than angle D. angle C is one of the congruent angles. What is the measure of each angle in triangle CDE? \n" ); document.write( "------------------- \n" ); document.write( "Let the vertex angle be \"x\" degrees. \n" ); document.write( "Each base angle is \"x+39\" degrees. \n" ); document.write( "----------- \n" ); document.write( "EQUATION: \n" ); document.write( "x + 2(x+39) = 180 \n" ); document.write( "3x + 78 = 180 \n" ); document.write( "3x = 102 \n" ); document.write( "x = 34 degrees (vertex angle measure) \n" ); document.write( "x+39 = 73 (each base angle meansure) \n" ); document.write( "=============================== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
