The answer is: [B]: " 60° " .
________________________________________
Because at whatever location, <span>∠2 and ∠4 are vertical angles;
</span>
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° " .

Answer:
x= 4, y=3
Step-by-step explanation:
2x + 3y = 17
3x - 2y = 6
----------
<u>If we double the first and triple the second equation, and add up, we can get rid of y:</u>
- 4x+6y= 34
- +
- 9x - 6y= 18
- -----------------
- 13x= 52
- x= 4
<u>Then it is easy to find the value of y:</u>
<u>Answer is</u>: x= 4, y=3
