Step-by-step explanation:
Answer:
x=55
Step-by-step explanation:
Ok I'm not sure about the theorem I thought it was just corresponding angles theorem but to get the x value set up an equation with your given info that is equal to 120.
2x+10=120
Subtract 10 from both sides.
2x=110
Divide both sides by 2.
x=55
It using the slope form which is (y=mx+b), in your case -3 is the m or slope and 2 is b or the y-intersect.
Step-by-step explanation:
The angle 2 and 3 are in vertically opposite sides. So, they are vertically opposite angles.
Hence, second option is correct.
