Question

160° А C B What is the mŁABC ?​

Answer 1

$\qquad\qquad\huge\underline{\boxed{\sf Answer☂}}$

By theorem : Angle made by an arc at the centre is double the angle made by the same arc on the circumference part of the circle.

Therefore~

$\qquad \sf  \dashrightarrow \: 2 \times \angle ABC = 160$

$\qquad \sf  \dashrightarrow \: \angle ABC = 160 \div 2$

$\qquad \sf  \dashrightarrow \: \angle ABC = 80 \degree$

I hope you understood ~
