Answer 2

Answer :

<ACD = 120°

Question :

To find angle.

Solution :

• Total degree of triangle = 180°
• To find angle:

⟹ Total degree of triangle - adding given angles

So,

1 st angle <A =75°

2 nd angle <B =45°

• <C = 180 - (75-45)
• = 180 -120

<C = 60°

⟹ 75 + 45 + 60 = 180°

We know that the line <ACD is in linear pair and because of this the total of <ACB and <ACD is 180°

• <ACB + <ACD = 180°

<ACB = 60°

180° - 60 = 120°

So,

⟹ <ACD = 120°

120 + 60 = 180
