EXAMPLES: robe communion sheinWebFirstly, we will use the fact that angles on a straight line add to 180 degrees. Specifically, \angle EFC and \angle CFG add to make 180\degree. Which means we can do the following: \angle CFG = 180\degree - 32\degree = 148\degree. Now, looking at the diagram we can see that angle \angle CFG and the missing angle x are corresponding angles. robe community newsletter
