To convert an angle from degrees to radians, multiply by π/180°.
Your angle is
(-280°)*(π/180°) = -14π/9
The appropriate choice is ...
B) (-14π/9)
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
