Step-by-step explanation:
The triangles are drawn below.
CD is perpendicular to AB as CD is height to AB.
Therefore, angles
°
So, triangles ΔCBD and ΔCAD are right angled triangles.
Now, from the right angled triangle ΔABC,

From ΔCBD,
is same as
.
So, 

Now, from ΔCAD,
is same as 
So, 

Hence, the unknown angles of both the triangles are:
