shouldnt iii be

cause its oa +1/2 ac but the answers have sqrt(3) +1 instead of the plus 2?

Let M be intersection of AC & BD and O the Origin

$\overrightarrow {OC} = \sqrt 3 + (1+\sqrt 3)i\\ \\ \overrightarrow {OA} = 1 \\ \\ \overrightarrow {OM} = \frac{1}{2} (\overrightarrow {OA} + \overrightarrow {OC}) = \frac {1}{2} (1 + \sqrt 3 + (1 + \sqrt 3)i) = \frac {1+\sqrt 3}{2} + \frac {1 + \sqrt 3}{2} i$

Note: M is midpoint of AC
