    sin(45° + θ) = sin(45°)(cosθ) + sin(θ)cos(45) = sqrt2/2

    Look at the problem as this instead. the solution should be immediately obvious.

    If you need another hint, ask away. i am happy to help.

    edit: the answer is a. once you simplify. hopefully you got that, but if you didn't, consider studying a lot more before any test or quiz
