CAN SOMEONE TELL ME WHAT (HIJ) IS IN THIS CIRCLE PLEASE

Answer:
180°
Step-by-step explanation:
[tex] m\angle JBG = 90\degree [/tex]... (given]
[tex] m\angle GBH = 180\degree - 90\degree= 90\degree [/tex]
(linear pair angles)
[tex] \implies \widehat{JGH} = 180\degree [/tex]
[tex] \implies \widehat{HIJ} = 360\degree - 180\degree [/tex]
[tex] \implies \widehat{HIJ} = 180\degree [/tex]
