Question

In the given fig, Angle ABC=70° and Angle ACB=30°. find Angle ADC Full Solution​

Answer 1

Answer:

∠ACB =   55° if O is the center of the circle and Angle ABD =35 and angle BAC =70

Step-by-step explanation:

∠ADB = ∠ACB     as both angles from same chord on same side

O lies on BD

Hence BD is Diameter

and∠DAB = 90°  

in Δ ABD

∠DAB  + ∠ADB + ∠ABD = 180°

=> 90° + ∠ADB + 35°  = 180°

=> ∠ADB = 55°

∠ADB = ∠ACB  

=> ∠ACB =   55° . please mark me as brainlist
