차(car) 기다려야 해서(기다리다 wait + -어야 하다 have to + -해서because) 집(house, home) 가면(가다go + -면if) 늦을 것 같아요(늦다be late + -을 것 같다seems to + -아요present verb ending). 차 기다려야 해서 집(에) 가면 늦을 것 같아요. (It seems that I will be home late because I have to wait for the car.)

Thank you very much.

Я думаю, что опоздаю, если пойду домой, потому что мне придется ждать.

차 기다려야해서 means literally "Because I have to wait for the car"
