Answer:
please can you indicate the question
You know from trigonometry that AB = 15 units, so the area of the larger triangle ACB is (1/2)*15*15 = 112.5 units^2.
Then the area of triangle ADE is
.. (112.5 -62.5) = 50 . . . . units^2
Try explaining how you worked the problem and how you did it
The vertex would be at (3, 6).
