Question

The equation to the base of an equilateral triangle is x + y = 2 and one of vertex is (2, -1). The length
of the side is 'a' then 3a2​

Answer 1

Step-by-step explanation:

Answer 2

Answer:

2

Step-by-step explanation:

Putting (2,-1) on line does not satisfy

so it lies on vertex opposite to line'

Now perpendicular distance from point to line is height

Height=1/$\sqrt{2}$

Height=$\sqrt{3}$/2*side=1/$\sqrt{2\\}$

So side=$\sqrt{2/3}$=a

a^2=2/3

3a^2=2
