(6+sqrt(3))/(6-sqrt(3))=a+b sqrt(3)

(3-sqrt(6))/(3+2sqrt(6))=a sqrt(6)-b

If |veca.vecb|=sqrt(3)|vecaxxvecb| then the angle between veca and vecb is (A) pi/6 (B) pi/4 (C) pi/3 (D) pi/2

If |veca.vecb|=sqrt(3)|vecaxxvecb| then the angle between veca and vecb is (A) pi/6 (B) pi/4 (C) pi/3 (D) pi/2

A pair of tangents is drawn to a unit circle with center at the origin and these tangents intersect at A enclosing an angle of 60^0 . The area enclosed by these tangents and the arc of the circle is 2/(sqrt(3))-pi/6 (b) sqrt(3)-pi/3 pi/3-(sqrt(3))/6 (d) sqrt(3)(1-pi/6)

A pair of tangents is drawn to a unit circle with center at the origin and these tangents intersect at A enclosing an angle of 60^0 . The area enclosed by these tangents and the arc of the circle is (a) 2/(sqrt(3))-pi/6 (b) sqrt(3)-pi/3 (c) pi/3-(sqrt(3))/6 (d) sqrt(3)(1-pi/6)

If the angle between line with d.cs (-(2)/(sqrt(21)), (a)/(sqrt(21)), (b)/(sqrt(21))) and other line with d.c ((3)/(sqrt(54)), (3)/(sqrt(54)), (-6)/(sqrt(54))) is 90^(0) then a pair of possible values of 'a' and 'b' respectively are

A pair of tangents are drawn to a unit circle with centre at the origin and these tangents intersect at the point P enclosing an angle of 60^(0). The area enclosed by the tangents and the arc of the circle is,(2)/(sqrt(3))-(pi)/(6) (b) sqrt(3)-(pi)/(3)(pi)/(3)-sqrt(3)(d)sqrt(3)(1-(pi)/(6))
