Answer:

$\huge{ \boxed{ \star{ \underline{ \mathtt{ \blue{ANSWER}{} }{} }{} }{} }{} }{}$

Correction in the question :-

<A = 75°

Solution :-

We are Given with a Triangle ABC where BC is extended to D.

To prove that,

• <ACD =?

Detailed Solution :-

According to the Exterior angle property,

• <ACD = <BAC+<ABC

• <ACD = 75°+45°

• <ACD = 120° [ Exterior angle property]

• Thus,<ACD = 120°
