Narrative:

I was approaching ZZZ at approximately xa:00 for pattern work. About 9 to 10 miles out; I made my first radio call to state my intentions before entering the pattern. 'ZZZ airport traffic; cessna X plane inbound 10 miles out; ZZZ airport traffic.' there was no radio communication from any other pilots; so I proceeded to enter left pattern on the downwind for runway xx. On downwind; I made another radio call. 'ZZZ airport traffic; cessna X on downwind for runway xx.' as I was turning left on base and notice incoming traffic at my 1 o'clock at the same altitude and coming in for the same runway. There wasn't no radio calls from the pilot coming from the east nor did they state their intention for ZZZ airport. Both planes were within 50 to 100 feet of each other.
