Anybody know the answer to this one

100 degrees

Step-by-step explanation:

So, since angle C is 40 degrees and the two blue lines symbolize angle C and angle B to be equal, angle B is also 40 degrees. We know that a triangle adds up to 180 degrees and if we add the ones that we kno 40+40=80. Now we just subtract 180-80=100

Hope this helped and God bless :)

100 degrees

Step-by-step explanation:

Sides AB and AC are equivalent, so if angle C is 40 degrees, then the adjacent angle, ( angle B ), is also 40. Since every angle must add up to 180 degrees total, we can find angle C using subtraction

180 - 80 = 100 degrees

ok so what's the question?
