#### Question

Calculate:

(i) ∠CDB, (ii) ∠ABC, (iii) ∠ACB

#### Solution

Here,

∠CDB = ∠BAC = 49°

∠ABC =∠ADC = 43°

(Angle subtend by the same chord on the circle are equal)

By angle – sum property of a triangle,

∠ACB = 180°- 49° -43°= 88°

Is there an error in this question or solution?

Solution Calculate: (I) ∠Cdb, (Ii) ∠Abc, (Iii) ∠Acb Concept: Chord Properties - Chords Equidistant from the Center Are Equal (Without Proof).
