50 COS 30 = 25.
So, it is correct answer.
So, it is correct answer.

50 SIN 30 = 25 for departure.

Departure is L Sin θ.

d = 50sin30 = 25m.

50 m is the AB how taken we In case of AC?

You are right @Civillian.

L sin α = 50 * sin 30 = 25 m.

I think the answer is 12.5m.
The given distance 50m is for line AB , so you cannot use it directly to solve for departure on line CA.
So using the triangle ABC , given the length of AB=50m and the angles can be computed using the given bearings. The side AC can be computed and AC=25m.
Then, the departure of line AC is 25sin(30)= 12.5m.
