Algebra.Com's Answer #468038 by josgarithmetic(39748) ![]() You can put this solution on YOUR website! SUPPLEMENTARY angles are angles which sum to 180 degrees. \n" ); document.write( "COMPLEMENTARY angles sum to 90 degrees. \r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "You are asking for some angle, x, such that x+215=90. Is this really what you want? If so, then good. Do it. \n" ); document.write( "x+215-215=90-215 \n" ); document.write( "x=-125 degrees. \n" ); document.write( "(That is, negative 125.)\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "This would be a rotation of the unit vector on the unit circle clockwise by 125 degrees. \n" ); document.write( " |
