Long cage derailler with 10 speed groupset

guys I have matched this rear derailler onto the wife's bike 9 speed tiagra 50/39/30 crankset,front derailler tiagra

was wondering would it work with 10 speed 105/ultegra 50/34 or 50/39/30 or is there a different long cage rear derailler for 10 speed

any help appreciated

IIRC, you can use derailleurs sold as 9 speed on 10 speed shimano systems - no difference

You probably don't need a long cage for a double, but it will still work.

My 8sp Sirrus came with a 9sp Tiagra mech and it seems to operate fine, I can't remember a problem with it in over 10,000 miles.
