Answer:

π/4, 7π/4

Explanation:

Adding √2 and dividing by 2 makes the equation ...

cos(θ) = (√2)/2

The first-quadrant solution is ...

θ = arccos((√2)/2) = π/4

The angle in the 4th quadrant with the same reference angle will have the same cosine value.

θ = 2π -π/4 = 7π/4

The two solutions are θ = π/4, 7π/4.
