## Answers ( No )

Answer:” 60° ” .

Step-by-step explanation:The answer is:

[B]:“60°” .________________________________________Because at whatever location, ∠2 and ∠4 are vertical angles;

and all vertical angles have equal measurements.

Given: m∠1 is 120°, and ∠1 is supplementary to ∠2 ;

then m∠1 + m∠2 = 180° .

So, m∠2 = (180 – 120)° = 60° .

As aforementioned:

m∠4 =m∠2= 60°; which is:Answer choice: [B]:”60°” .___________________________________________________
