Consider a horizontal plane (contains north south east west direction ). Let's consider a point "A" which is starting point  firstly it travels 400 m north from A and then 300 m south ..it implies it is 100 meter far from point "A" .then it travels 1200 meter vertically upward (imagine like coming out of horizontal plane we have considered) and now displacement(x) would be distance between point A" and point 1200 meter above plane .x^2=(1200)^2+(100)^2
X=1204.2 metres

DO YOU PLAY LOTTERY??

I will assume you do or you wouldn't have ended up here on this webpage. But do you WIN the lottery? I will assume you don't, or you wouldn't have ended up here on this webpage.

My name is James M. Mason, If you want a spell to win the lottery, look no further. Dr. Lucas lottery spell is amongst the most powerful spells I have experienced, and you will feel the power once He is done with your lottery spell.

The spell uses a wide range of magical sources, then combines and funnels those energies into one single "beam" of luck attracting, destiny controlling, wealth manifesting pure magical power.

Incorporating herbs, candles, the elements and much more simple magical techniques, this spell can be cast in a few minutes using a few very simple ingredients in His temple.

I am a living witness of his power because he just helped me with his lottery spell and I won CASH FOR LIFE LOTTERY, I'm so happy right now. Thanks to you Dr. Lucas. Contact Him through his private What's App Number +15302120104.
Whichever type of lottery you play, HE can use His lottery spell to help you win.
