Question

plzzz sol this plane it in easily manner please ​

Answer 1

Step-by-step explanation:

one vertex is at origin

OB = 2a units

vertex B is 2a units from origin

==> coordinates of B is ( 2a , 0)

draw an altitude from A to OB it will also be the median because OAB is an equilateral triangle

let it intersect OB at P

P is midpoint of OB

==> coordinates of P is (0 , a)

as OB is in x axis and AP is perpendicular to OB

AP is parallel to y axis

now in triangle APB is right angled at P , AB = 2a , PB = a

==> by pythogorous theorem AP = root(3)a

A is at at a distance of root(3) from P and is parallel to y axis

==> coordinates of A is (a , root(3)a)

here is your answer

O(0,0) ; B(2a , 0) ; A( a , root(3)a)

mark this as brainliest

Answer 2

by applying distance formula we can get the answer
