Answer 1

given $\implies$

AB = AC

$\boxed{solution}$

$\implies$ $\angle$ ACB = 180⁰ - $\angle$ C

$\implies$ $\angle$ ACB = 180⁰ - 100⁰

$\implies$ $\angle$ ACB = 80⁰ ( linear pair )

again ,

$\angle$ ABC = $\angle$ ACB

( base angles are equal in an isosceles triangle )

$\therefore$ $\angle$ ABC = 80⁰
