The value of (sin 43° cos47° + cos43° sin47°)

⇒ Option B is correct as it satisfy the value

Given, sin43°cos47° + cos43°sin47°

Need to find the value

⇒ sin43°cos(90 - 43)° + cos43°sin(90 - 43)°

⇒ sin43°sin43° + cos43°cos43°

⇒ sin²43° + cos²43°

= 1

[Since, sin²θ + cos²θ = 1]

⇒ Option A is incorrect because by solving the equation we get the value as 1

⇒ Option C is incorrect because by solving the equation we get the value as 1

⇒ Option D is incorrect because by solving the equation we get the value as 1
