Find the equation of a line for which p = 5, α = 60°

Answer»

Given: p = 5, α = 60° 

Concept Used: 

Equation of line in normal form. 

Explanation: 

So, the equation of the line in normal form is 

Formula Used: 

x cos α + y sin α = p 

x cos 60° + y sin 60° = 5

 ⇒ \(\frac{x}{2}+\frac{\sqrt{3y}}{2}=5\)

⇒ x + √3y = 10 

Hence, the equation of line in normal form is x + √3y = 10.
