A line forms a triangle of area `54sqrt(3)s q u a r e`units with the coordinate axes. Find the equation of the line if theperpendicular drawn from the origin to the line makes an angle of `60^0`with the X-axis.

Answer» Equation of AB
`y=mx+c`
Equation of OD
`y-0=tan60(x-0)`
`u=sqrt3x`
`(m_(AB))sqrt3=-1`
`m_(AB)=-1/sqrt3`
Equation of line
`y=-1/sqrt3x+c`
`1/2*(sqrt3C)*C=54sqrt3`
`C^2/2=54`
`C^2=108`
`C=sqrt108`
`y=mx+c`
`y=(-1/sqrt3)x+sqrt108`.
