The area of △ABC is approximately _____ units2. Answer by jorel1380(3719) (Show Source):
You can put this solution on YOUR website! First, to find the length of DB, we get:
5.9²+DB²=6²=36
DB²=1.19
DB=1.091
Area ADB=1/2 (5.9)(1.091)=3.22
Area ADC=1/2 (5.9)(7+1.091)=23.87
Area ABC=23.87-3.22=20.65 units. ☺☺☺☺
