Answer 2

`\huge\boxed{♧ \: \mathfrak{ \underline{Answer} \: ♧}}`

here's the solution,

• 
  `\pi = 180`

• 
  `(\pi)/(3) = (180)/(3)`

• 
  `(\pi)/(3) = 60`

=》

`f( \theta) = \cos( \theta) + 2 \cos( ( \theta)/(2) )`

=》

`f(60) = \cos(60) + 2 \cos( (60)/(2) )`

=》

`f(60) = (1)/(2) + 2 \cos(30)`

=》

`f(60) = (1)/(2) + (2 * ( √(3) )/(2))`

=》

`f(60) = (1)/(2) + √(3)`

=》

`f(60) = (1 + 2 √(3) )/(2)`

hence, correct option is C.
