Hlww Hi Nope its first equation 6x + 2√3y = 12 or 3x + √3y = 6 -----(i) Thanx:) solving it,x² + y² = x² -6x + 9 + y² - 2√3y + 3 Oh I got it? The triangle is equilateral so √(x-0)²+(y-0)² = √(x-3)²+(y-√3)² Let the cordinates be x,y U can solve it by distance firmula ? Its oral question! Answer is 3,-√3 |
