Hi friend
---------------
Your answer
--------------------

Here,

Given that : - Seg AB if the diameter.

Angle CAB = 50°

To find : - Angle CDA = ?

Now,
----------

Angle CAB = Angle BDC [Angle in the same Segment are equal.]

Then, Angle BDC = 50°

Again,
-----------

Angle BDA = 90° [Angle in a semicircle is a right angle.]

But,

Angie BDA = Angle CDA + Angle BDC

=> 90° = Angle CDA + 50°

=> Angle CDA = 90° - 50°

=> Angle CDA = 40°

HOTE IT HELPS
