Answer :

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
