Find the equation of the line on which the perpendicular from the origin makes an angele of 30⁰ with the x axis and which forms a triangle of area 50/3 with the coordinate axes. 

In the representation of  on number line we follow following steps of construction.

• Draw AB = x units.
• Extend AB upto C such that AC = x + 1.
• Draw perpendicular bisector of AC let O is the mid-point of AC.
• Draw semicircle of radius = OA and centre O.
• Draw perpendicular from B which intersect semicircle at D.

Let M is the mid-point of OD. If BM =9.5 then find the number which is being represented.
