Answer:

270°

Step-by-step explanation:

a reflex angle is an angle which is larger than 180° but smaller than 360°

an angle around a point is 360°

so to find angle B we do [tex]360-90[/tex] to give 270

so angle B is 270°

Alr because you know the A is 90 and a full circle is 360 so in order to find B you need to subtract A from 360 which is 90-360= your answer (which you told me not to tell you)
