((AB)/(AD))=((AC)/(AE))=((√3)/2)  ⇒ΔABC∼ΔADE  ⇒α=β  ?=α+60°+90°−β=150° ✓
$$\frac{{AB}}{{AD}}=\frac{{AC}}{{AE}}=\frac{\sqrt{\mathrm{3}}}{\mathrm{2}} \\ $$$$\Rightarrow\Delta{ABC}\sim\Delta{ADE} \\ $$$$\Rightarrow\alpha=\beta \\ $$$$?=\alpha+\mathrm{60}°+\mathrm{90}°−\beta=\mathrm{150}°\:\checkmark \\ $$
