Question

A circle has a diameter  AB
  and an inscribed angle at vertex  C
  forming triangle  ABC
 . The measure of angle  A
  is 27°. Using what you know about inscribed angles, what is the angle measure of  B
 ?(1 point)
m∠B=
 
º

GPT-5 mini · Answer

m∠B = 63°

Reason: AB is a diameter so the inscribed angle at C subtending AB is 90°. Then B = 180° − 90° − 27° = 63°.
