Since FGE=50, that would mean FGH would equal 180-50, since the angles are supplementary. Next, since we know AD and HE are parrallel, that would mean FGE=BCD and FGH=BCA=130.

Answer:

BCA = 130

Step-by-step explanation:

FGE = 50

FGE + GEC + ECG = 180

50 +90 + ECG = 180

140 + ECG = 180

Subtract 140 from each side

140-140 + ECG = 180-140

ECG = 40

ECG and BCJ  are vertical angle, so they are equal

JCA and GEC are corresponding angles so they are equal

We are looking for BCA

ACJ + BCJ = BCA

ACJ + BCJ = BCA

90 + 40 = BCA

130 = BCA
