is this the right way to find an angle?

trying to take a weapon turret and a target and rotate the weapon to aim at the target.

I'm not just rotating though because the weapon has a horizontal and vertical dial so i want to really do 2 rotations at once and I think that means i basically need to find 2 angles, the x angle and the y angle and rotate seperatly each dial on the right axis the right amount. I'm also working within angle constraints so weapons don't have 360 views.

because i'm doing 2 rotations instead of 1 it seems like i should be doing 2 2d rotations so i'm using vector2 not vector3.

for the x rotation i'm ignoring the y axis and for the y im ignoring the x.

 vector2 XWeapon;
 vector2 XTarget;
 vector2 YWeapon;
 vector2 YTarget;
 
 
             XWeapon.x = WeaponTransform.position.x;
             XWeapon.y = WeaponTransform.position.z;
             
             YWeapon.x = WeaponTransform.position.y;
             YWeapon.y = WeaponTransform.position.z;
             
             XTarget.x = AimPoint.x;
             XTarget.y = AimPoint.z;
             
             YTarget.x = AimPoint.y;
             YTarget.y = AimPoint.z;
             
             XAngleToTarget = Vector2.Angle(XWeapon,XTarget);
             YAngleToTarget = Vector2.Angle(YWeapon,YTarget);

I'm just wanting someone to confirm to me that that looks like the right way to do it (so it'll work, i'll be testing of course but i want to make sure in principle it should work) and that i'm not going the long way about doing it.
