It is given that ∠BCD = 100° and ∠ABD = 70°
We have to find the ∠ADB
∠A + ∠C = 180° (Opposite pair of angle of cyclic quadrilateral)
Now in is and
ABCD is a cyclic quadrilateral. If ∠BCD=100∘ and ∠ABD=70∘, then find ∠ADB.
In the figure, ABCD is a cyclic quadrilateral, If ∠BCD=100∘ and ∠ABD=70∘, find ∠ADB
