What is the 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.

answer: they are supplementary angles

step-by-step explanation: 161+19=180. supplementary angles equal 180 degrees
