$\huge\bf \sf{It \: is \: given \: that:-)}$


▶
$\bf{ABCD \: is \: a \: parallelogram.}$

▶
$\bf{ \angle D = 120°. }$


$\huge \bf \sf{To \: find :-)}$


$\boxed{ \angle A = ? .}$


=> AB || CD [ ABCD is a parallelogram ].

=> and AD is a transversal.


$\bf \underline{ \angle D + \angle A = 180°.......[ Co - interior \: angle ].}$

$\bf{=> 120° + \angle A = 180°.}$


$\bf{=> \angle A = 180° - 120°.}$


$\huge \boxed{=> \angle A = 60°.}$


✅✅ Hence, angle A is founded ✔✔.



$\huge \boxed{THANKS}$
