Answer 2

Answer:

$\huge\color{lightgreen}\boxed{\colorbox{black}{Answer ☘}}$

in the given figure...

$m∠2 = 39° \\ also... \\ m∠2 = m∠4 = 39° \\ (vertically \: opposite \: angles) \\ \\ = > now.. \: m∠1 + m∠2 = 180° \\ (angles \: on \: a \: straight \: line) \\ = > m∠1 = 180° - m∠2 \\ = > m∠1 = 180° - 39° \\ = > m∠1 = 141° \\ \\ also... \\ m∠1 = m∠3 = 141° \\ (angles \: on \: a \: straight \: line)$
