Answer: A 28.50 sq. u
Step-by-step explanation:
In the given figure , radius of the circle : r= 10 u
Central angle made by Arc ED:
= 90° ( right angle )
Now , the area of the segment is given by :-
Area of segment = Area of sector (ECD) - Area of triangle(ECD) (i)
Formula : Area of right triangle = 0.5 x Base x Height
Area of sector = 
Using above formulas in (i) and substituting corresponding values , we get
Area of segment =

Hence, the correct answer is A 28.50 sq. u
X=6-3y
4(6-3y)+6y=-6
24-12y+6y=-6
24-6y=-6
-6y=-30
y=30/6
y=5
x+3 (5)=6
x+15=6
x=-9. (-9,5) <------------
