Respuesta :

reflex angle is 360 - the angle, thus a reflex angle of right ang is 360 - 90 = 270

270

Reflex angles are the angles which measure more than 180 ° and less then 360°

So angle ABC = 90°
therefore the reflex angle can be
360 - 90
= 270

Which is less than 360 and greater than 180

So,
The measure of <ABC 's reflex angle is 270
