Answer 2

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

here's the solution,

• $\pi = 180$

• $\dfrac{\pi}{3} = \dfrac{180}{3}$

• $\dfrac{\pi}{3} = 60$

=》

$f( \theta) = \cos( \theta) + 2 \cos( \frac{ \theta}{2} )$

=》

$f(60) = \cos(60) + 2 \cos( \frac{60}{2} )$

=》

$f(60) = \dfrac{1}{2} + 2 \cos(30)$

=》

$f(60) = \dfrac{1}{2} + (2 \times \frac{ \sqrt{3} }{2})$

=》

$f(60) = \dfrac{1}{2} + \sqrt{3}$

=》

$f(60) = \dfrac{1 + 2 \sqrt{3} }{2}$

hence, correct option is C.
