Answer: 63
Step-by-step explanation:
The inner angles needs to add up to 180, so (BAC) angle+ x + 65= 180.
Also whrn you cut a direct line each angle you just had need to add up to 180 as well. So (BAC) +128 = 180.
BAC is 52, when you put it in the first equation lt would make x=63.
2. Option(shorter)
If you flip the 2nd on equation and add the sides of the equation you would have,
(BAC) + x+ 65 + 180 = 180 + (BAC) + 128
If I erased the (BAC)s and 180s since they are the same thlngs we would be left with x + 65 = 128
It actually means that of you put two inner angles together you would get the outer angle that is next to the third angle.
