If sin(A - B) = $$\frac{1}{2}$$ and cos(A + B) = $$\frac{1}{2}$$ where A > B > 0$$^\circ$$ and A + B is an acute angle, then the value of A is:
Given, Â sin(A - B) = $$\frac{1}{2}$$
$$\Rightarrow$$ Â sin(A - B) = sin 30$$^{\circ\ }$$
$$\Rightarrow$$Â A - B = 30$$^{\circ\ }$$ ........(1)
cos(A + B) = $$\frac{1}{2}$$ and A + B is an acute angle
$$\Rightarrow$$ Â cos(A + B) = cos 60$$^{\circ\ }$$
$$\Rightarrow$$Â A + B = 60$$^{\circ\ }$$ ........(2)
Adding equations (1) and (2),
2A = 90$$^{\circ\ }$$
$$\Rightarrow$$Â A = 45$$^{\circ\ }$$
Hence, the correct answer is Option C
