Make a navmesh object start moving in a circle around an object

When my enemy gets within so close to the player it is supposed to start to circle around it. I kind of have this working as I am able to get it to circle around the player without any issue, however what I can not get is for the enemy to start in the correct spot on the circle. As in, when the enemy starts making its circle I want it to start where it is. Instead it moves to a random position on the circle then starts. This is my code so far.

      targetDir = mEnemy.transform.position - mEnemy.myTarget.transform.position;
     targetDir.y = 0;
     Debug.DrawRay(mEnemy.myTarget.transform.position, targetDir * 5, Color.red, 20f);
     Debug.DrawRay(mEnemy.myTarget.transform.position, mEnemy.myTarget.transform.forward * 5f, Color.red, 20f);
     float angle = Vector3.Angle(mEnemy.myTarget.transform.forward, targetDir);
     Debug.Log(angle);
     theta = angle * (Mathf.PI / 180);
     Debug.Log(theta);
     x = Mathf.Cos(theta) * 5 + mEnemy.myTarget.transform.position.x;
     y = mEnemy.transform.position.y;
     z = Mathf.Sin(theta) * 5 + mEnemy.myTarget.transform.position.z ;
     pos.x = x;
     pos.y = y;
     pos.z = z;
     mEnemy.agent.SetDestination(pos);

I really don't understand why this is not working as my debug tests are showing me that I do indeed have the correct theta. What is wrong with my math?
