Answer :

Given: p = 8 and = 1500


Here p is the perpendicular that makes an angle with positive direction of x-axis , hence the equation of the straight line is given by:


Formula used:


x cos + y sin =p


x cos 1500 + y sin 1500 =8


i.e; cos 1500 = cos ((4360) +60) = cos((42 )+60)= cos 60


similarly, sin 1500 = sin ((4360) +60) = sin((42 )+60)= sin 60


hence, x cos 60 + y sin 60 =8


x (1/2)+ y (/2)=8


Hence The Required equation of the line is x + y = 16.
