Option B is NOT correct because, if there's only one segment, we cannot form a vertex.
See the image below for an example:
Answer:
see explanation
Step-by-step explanation:
Given
2cosΘ - = 0 ( add
to both sides )
2cosΘ = ( divide both sides by 2 )
cosΘ =
Since cosΘ > 0 then Θ is in first and fourth quadrants, hence
Θ = (
) =
OR
Θ = 2π - =
solutions are Θ = ,
