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
