This angle is 90 degrees.

I have recently started a new job.

I think he should be treated preferentially.

In the train, the priority seat is for the elderly and pregnant women.

It's difficult to decide the priority of work.

I have been to France once.

He finished all his work all at once.

The feeling of satisfaction after completing this job is irreplaceable.

He was dissatisfied with the result.

I think his actions are just for self-satisfaction.
