Somebody pls help me on this problem.
I will see if I can get the image up. Melody.
Hint: AABD = AABC - (ABCE + AADE)
ABCE = (2 * 7) / 2 = 7 u2
1/ Calculate angles AED and EAD
2/ By using the law of sines, calculate unknown sides AD and ED
3/ Use Heron's formula to calculate the area of triangle ADE
