i've got a new job after long time study in collapse. But, my boss was angry with me with no reason. Should i quit this job?

There's not enough information here for us to help you. Only you can know how much you need this job, whether you can make amends with your boss and be okay going forward, or alternatively, if you quit, how hard it would be to find another job. As a rule, I wouldn't quit a job because of one bad interaction with a supervisor, unless there were some very unusual circumstances.
