Question

could someone please tell me the ans
no irrelevant and assumed answers pls​

Answer 1

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
