Answer 2

A B is hypotenuse of two right triangle A C B and ADB.

⇒  ∠ACB=90  

The

 and ∠ADB=90  

The

.

⇒  ∠ACB+∠ADB=90  

The

+90  

The

=180  

The

 

Sum of opposite angles of a quadrilateral A C B D is supplementary.

∴  Quadrilateral A C B D is a cyclic quadrilateral.

⇒  ∠BAC​ and ∠BDC​ are made by the same arc BC.

We know that, angles made in same arc are equal.

∴ ∠BAC=∠BDC
