21(-4,4) and (6,-1) are the end points of the diameter of circle.....so eq of circle can be easily evaluated....after that everything is but obvious and can be easily solved....
I know this is an easy one, but don't know why I am not getting the right answer.
The extremeties of a diagnol of rectangle are (-4,4) and (6,-1). A circle circumscribes the rectangle and cuts an intercept AB on the y-axis. The area of the triangle formed by AB and the tangents to the circle at A and B is :-
(a) 1233 / 8 sq units (b)1233 sq units
(c) 363/8 sq units (d) none
