$\huge{\textbf{{{\color{navy}{៚An}}{\red{sw}}{\pink{er࿐}}{\color{pink}{:}}}}}$

$\huge{\color{magenta}{\fbox{\textsf{\textbf{VERIFIED✅}}}}}$

Here , ∠AOE + ∠ BAO= 180°

=> ∠AOE = 180- 60 = 120° ( BAO = 60°)

Now , ∠ COD = ∠AOE = 120° (Vertically opposite angle)

In Triangle COD,

A + 25° + 120° = 180° ( Angle sum property of a triangle is 180 degree )

a + 145 ° = 180 °

a= 180° - 145 °

a= 35°

HOPE IT HELPS
