268


Hopefully that helps

Answer 2

Answer:

268°

Step-by-step explanation:

$In\: \odot O,$ AB is diameter.

So, $\widehat{AB} \:\&\: \widehat {BA}$ are semicircular arcs.

$\therefore m\widehat {AB} =m\widehat {BA} = 180\degree$

$\because \: m\widehat {BC} = m\widehat {BA} - m\widehat {CA}$

$\therefore \: m\widehat {BC} = (180-92)\degree$

$\therefore \: m\widehat {BC} =88\degree$

$\because m\widehat {ABC} = m\widehat {AB}+m\widehat {BC}$

$\therefore m\widehat {ABC} = 180\degree+88\degree$

$\therefore m\widehat {ABC} = 268\degree$
