Please help! Need answer ASAP!

Answer 1

 We start with the following fact:
 ∠1 and ∠2 are supplementary angles
 Therefore, the following equation is valid:
 m∠1 + m∠2 = 180
 We clear the angle 2:
 m∠2 = 180-m∠1
 Substituting values:
 m∠2 = 180-120
 m∠2 = 60
 Then, we have:
 ∠2 and ∠4 are vertical angles
 Vertical angles are a pair of angles (not adjacent) opposed to each other when two lines intersect
 Thus:
 m∠2 = m∠4 = 60
 Answer:
 the measure of ∠4 is 60 °
