Question

6. The length of the perpendicular from origin on a
line is 5 and this perpendicular is inclined at an
angle of -60° with the x-axis. Find equation of the
line, compare it with ax+by+c=0. Write the
value of a​

Answer 1

Answer:

Explanation:

The equation of the line is xcos alpha+ysin alpha=p

where alpha=-60

p=5

Equation of line is x cos(-60)+y sin(-60)=5

x cos(60)-y(sin 60)=5

x/2-y($\sqrt{3}$/2)=5

x-y($\sqrt{3)}$=10

comparing with ax+by+c=0

a=1
