Algebra.Com's Answer #679597 by jorel1380(3719)![]() ![]() You can put this solution on YOUR website! First, to find the length of DB, we get: \n" ); document.write( "5.9²+DB²=6²=36 \n" ); document.write( "DB²=1.19 \n" ); document.write( "DB=1.091 \n" ); document.write( "Area ADB=1/2 (5.9)(1.091)=3.22 \n" ); document.write( "Area ADC=1/2 (5.9)(7+1.091)=23.87 \n" ); document.write( "Area ABC=23.87-3.22=20.65 units. ☺☺☺☺ \n" ); document.write( " \n" ); document.write( " |
