Can't get correct angle between two world positions

Question

I want to get the angle from transform.position to TargetPos, and apply it to transform.eulerAngles.y.

I can calculate a target position and apply it to the line renderer, which draws the line perfectly:

         TargetPos = StartPos + new Vector3(Random.Range(-1f, 1f), 0f, Random.Range(-1f, 1f)) * _dist;

         lineRend.SetPosition(0, transform.position);
         lineRend.SetPosition(1, TargetPos);

If I try to get the angle, it just returns a small, one-digit value.

     // Set direction
     float TargetDir = Vector3.Angle(transform.position, TargetPos);

     // Set rotation
     Vector3 rot = transform.eulerAngles;
     rot.y = TargetDir;
     transform.eulerAngles = rot;

How can I make this work? Thanks!

Fixed by using Vector2 instead:

     Vector2 vecTarget = new Vector2(TargetPos.x, TargetPos.z);
     Vector2 vecCurrent = new Vector2(transform.position.x, transform.position.z);

     float TargetDir = Vector2.SignedAngle(vecTarget - vecCurrent, new Vector2(0, 1));
