Q. 12 A13.8( 5 Votes )

# The value of (sin 43° cos47° + cos43° sin47°)A. 0B. 1C. sin4°D. cos4°

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
