Answer:
Angle 2 = Angle 4 ( vertically opposite angles)
3 possible solutions.
The reason is because of the degree, which is 3
------------------------(- K)-------------0-------------(+K)-----------------
K unit to the left of 0, means K is negative.
The opposite of (-K) is (+K), both are symmetric vs. the origin "0", then its location will be +K
I believe it’s true not 100% sure
