​

Answer 1

Answer:

135°

plz do check my answer coz i am not sure

Answer 2

$Given \: AB \:and \:CD \:are \:two \: straight \\lines \: intersecting \:at\:O$

$\angle {AOC} = \angle {BOD} = x$

$\blue {( Vertically \: opposite \: angles )}$

$\Angle {AOC} + \angle {AOD} = 180\degree$

$\blue {( Linear \:pair )}$

$\implies \angle {AOD} = 180\degree - \angle {AOC}$

Or

$\implies \angle {AOD} = 180\degree - \angle {BOD}$
