Algebra.Com's Answer #496734 by tommyt3rd(5050)![]() ![]() You can put this solution on YOUR website! The sum of the measures of the angles of a triangle is 180 degrees. The measure of a right angle is 90 degrees. Therefore A+B+C=180, A+90+C=180, A+C=90 , and so A and C are complementary \n" ); document.write( " |
