a straight line is 180 degrees so we can find C by subtracting 140 from 180

180-140 = 40 degrees

all 3 inside angles need to equal 180 so now we have

180 = 40 + (2x) + (x+2)

180 = 40 +3x +2

180=42+3x

138=3x

x= 138/3 = 46

check : 2x= 2*46 = 92

x+2 = 46+2 = 48

92 +48 +40 = 180

so x = 46 degrees

so angle B = 2x46 = 92 degrees
