area of the triangle formed by the tangents at the points `(4, 6), (10,8)` and `(2, 4)` on the parabola `y^2 - 2x = 8y - 20,` is in sq. units)

If the area of the triangle formed by the points (1,2) , (2,3) , (x,4) is 40 sq.units, then x is

The area of the triangle formed by the tangent to the curve y=(8)/(4+x^(2)) at x=2 on it and the axes is

The area of the triangle formed by the tangent to the curve y=(8)/(4+x^(2)) at x=2 and the co-ordinate axes is

If the area of the triangle formed by the points (1,2),(2,3),(x,4) is 40 sq.units,then x is

The angle between the tangents drawn form the point (3, 4) to the parabola y^(2)-2y+4x=0 , is

The angle between the tangents drawn from the point (2, 6) to the parabola y^(2)-4y-4x+8=0 is

The tangents at the end points of any chord through (1,0) to the parabola y^(2)+4x=8 intersect

Thangents are drawn from (-1, 0) to y^2 = 4x . Then the area of the triangle fromed by the tangents and the chord of the contact is : (A) 8 sq. units (B) 2 sq. units (C) 4 sq. units (D) 1 sq.units
