Answer:
angle BDE = 360° - (75° + 65° + 105°)
= 115°
So angle ADE= 180° - 115° = 65°
Also, angle AED = 180° - 105° = 75°
In triangle ADE
Side opp to angle A / Side opp to 65° angle
= DE / AE = 8/16 = 1/2 ...(i)
In triangle ABC
Side opp to angle A / Side opp to 65° angle
= BC / AB = 10/AB ...(ii)
Equating (i) and (ii)
1/2 = 10/AB
=> AB = 20cm
Thus, AB = 20cm
Hope this helps
