Answer:

y = π/3

Explanation:

To find the value of y, we can use the trigonometric identity for the sum of angles:

sin(x + y) = sin x * cos y + cos x * sin y

Comparing this with the given equation:

sin(x + y) = 1/2(sin x) + √3/2(cos x)

We can equate the corresponding terms:

sin x * cos y = 1/2(sin x) ----(1)

cos x * sin y = √3/2(cos x) ----(2)

From equation (1), we can see that cos y = 1/2.

From equation (2), we can see that sin y = √3/2.

To determine the values of y, we can use the trigonometric values of cosine and sine in the first quadrant of the unit circle.

In the first quadrant, cos y is positive, so cos y = 1/2 corresponds to y = π/3 (60 degrees).

Similarly, sin y is positive, so sin y = √3/2 corresponds to y = π/3 (60 degrees).

Therefore, the value of y is y = π/3 (or 60 degrees).
