What is the right thing to do?

Because you are coming from a side road with a “Give way” sign, you must let all traffic on the priority road go first.

The small additional sign under the “Give way” sign shows the course of the priority road: it bends from straight ahead to the right. That means both the motorcycle coming from the left (going straight across) and the blue car coming from the right (following the priority road) are on the priority road relative to you. So you must give way to both of them.

Rule of thumb for similar questions: A “Give way” sign always means you wait for everyone on the priority road, even if the priority road bends and even if the other vehicles are coming from different directions. Only after the priority road is clear may you drive out.
