How to translate an object in an unknown angle ?

I’m creating a sort of tps and I want to shoot a bullet in the rotation position of the player but it dosn’t work. Here the part that create the bullet and shot it (supposed to shot it). I don’t really understand why it’s not working.

void shot()
        float angleX = transform.rotation.eulerAngles.x;
        float angleZ = transform.rotation.eulerAngles.z;

        float posPlayerX = transform.position.x;
        float posPlayerZ = transform.position.z;

        Instantiate(bullet, new Vector3(posPlayerX+2, 0.44f, posPlayerZ), Quaternion.identity);
        bullet.transform.Translate(Mathf.Cos(angleX) * bulletSpeed * Time.deltaTime, 0f, Mathf.Sin(angleZ) * bulletSpeed * Time.deltaTime);

Thanks for helping

because you need to call translate method in the uppdate so it gets called every frame not only once when is created
