Answer 2

Answer:

Step-by-step explanation:

I think a error in the question it will be

Sin45× cos30 + cos45× sin 30

Then,

sin 45° = 1/√2

cos 30° = √3/2

cos 45° = 1/√2

sin 30° = 1/2

sin 45° × cos 30° - cos 45° × sin 30°

1/√2 × √3/2 - 1/√2 × 1/2

1/√2 × 1/2 × ( √3 - 1 )

√2/2 × 1/2 × ( √3 - 1 )

√2 / 4 × ( √3 - 1 ) ( Ans )
