I see.
to ask and answer i use google
In \(△ADB,∠ADB=(180−18−30)^∘=132^∘\) Applying sine law in \(△ADB\), \(\Large\frac{AB}{sin132^∘}=\frac{AD}{sin30^∘}⟹AD=\frac{AB}{2sin48^∘}\) as \(sin132^∘=sin(180−132)^∘=sin48^∘\) \(∠ABC=∠BAC=\Large\frac{1806^∘−96^∘}{2}=42^∘\) Applying sine law in \(△ABC\), \(\Large\frac{AC}{sin42^∘}=\frac{AB}{sin96^∘}⟹\frac{AC}{AB}=\frac{sin42^∘}{sin96^∘}=\frac{cos48^∘}{2sin48^∘cos48^∘}\) (applying \(sin~2A=2~sin~A~cos~A\)) So, \(AC=\Large\frac{AB}{2sin48^∘}⟹AC=AD\) So, \(∠ACD=∠ADC=\Large\frac{(180−24)^∘}{2}=78^∘\)
AWESOME YOU ARE SOOO COOL
