In the figure, with ∠BAC=40∘, what is the measure of ∠ABC (in degrees)?
The measure of ABC is 20 degrees... boomer
Angle(FHG) = 180 - 135 = 45
Angle(FGH) = 180 - 105 = 75
Angle(HFG) = 180 - (45 + 75) = 60
Angle(DFC) = angle(HFG) = 60
Angle(FDC) = 180 - 119 = 61
Angle(DCF) = 180 - (60 + 61) = 59
Angle(BCA) = 180 - 59 = 121
Angle(CBA) = 180 - (40 + 121) = 19
