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 * \angle ABC = 160`

`\qquad \sf  \dashrightarrow \: \angle ABC = 160 / 2`

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

I hope you understood ~
