Paramecium is a single-celled protozoan. The hair-like structures called cilia present on the paramecium help in collecting the food and movement. They sweep the food inside the paramecium through the oral groove.

In the given figure,, BC is a diameter of circle and ∠BAO = 60∘ . Then, ∠ADC

Nakshatra Yadav 2 years, 1 month ago

Given: BC is a diameter of circle ∠BAO = 60° ...(1) In ∆OAB, OA = OB ∴ ∠OAB = ∠OBA = 60° (angles opposite to equal sides are equal) ...(2) Also, ∠AOC = ∠OAB + ∠OBA (exterior angle) ⇒ ∠AOC = 60° + 60° (From (2)) ⇒ ∠AOC = 120° ...(3) We know, the angle subtended by an arc at the centre is twice the angle subtended by it at the remaining part of the circle. Thus, ∠AOC = 2∠ADC ⇒ 120° = 2∠ADC (From (3)) ⇒ ∠ADC = 60° Hence, ∠ADC = 60°.
