If one vertex of an equilateral triangle is at `(2.-1)` 1base is `x + y -2 = 0`, then the length of each side, is

If one vertex of an equilateral triangle is at (2.-1) lbase is x+y-2=0, then the length of each side,is

If one vertex of equilateral Delta is at A (3, 4) and the base BC is x + y - 5 = 0, then the length of each side of the Delta is

The vertex of an equilateral triangle is (2,-1) and the equation of its base is x+2y=1. The length of its sides is

If the equation of the base of an equilateral triangle is 2x - y=1 and the vertex is (-1,2), then the length of a side of the triangle is-

If the equation of the base of an equilateral triangle is 2x - y=1 and the vertex is (-1,2), then the length of a side of the triangle is-

If the equation of base of an equilateral triangle is 2x-y=1 and the vertex is (-1,2), then the length of the sides of the triangle is

If the equation of base of an equilateral triangle is 2x-y=1 and the vertex is (-1,2), then the length of the sides of the triangle is sqrt((20)/(3)) (b) (2)/(sqrt(15))sqrt((8)/(15)) (d) sqrt((15)/(2))
