'ärgerlich' and 'frustrierend' both describe something negative that causes bad feelings. 'ärgerlich' is more general: something can be 'ärgerlich' if it is bothersome, annoying, or causes trouble. A person can also be 'ärgerlich' when they are annoyed. 'frustrierend' fits especially when you make an effort but do not succeed or do not reach a goal. So it is more strongly about disappointment and the feeling of not making progress. A lost key is 'ärgerlich'; many unsuccessful attempts are 'frustrierend'.
