If BD and EG are parallel lines and m/GFH = 50°, what is m/BCF?

Answer 1

130°

Explanation:

m of angle BCF is the same as the measure of angle EFH since they are corresponding. However, angle EFH is supplementary to angle GFH meaning the measurements have to add to 180. If the measure of angle EFH is 130°, then the measure of angle BCF is also 130°.
