Answer:
Any line through P(3,4) making an angle
6
π
with x−axis is
cos30
o
x−3
=
sin30
o
y−4
=r
Where r represents the distance of any point on this line from the given point P(3,4)
Any point Q on it is (r
3
/2)+3,(r/2)+4 and Q lies on 12x+5y+10=0
∴12[(
2
r√3
)+3]+5(

r
+4)+10=0
∴(12

+5)r+132=0
∴r=
12√(3)+5
∣−132∣
=
12√(3)+5
132
