Hello.
We know that a=100º.
b+a+f=180º
then we have
30º+100º+f=180º -------------> f=50º.
Since f and c are opposite angles by the vertex then f=c=50º. SUFFICIENT.
Therefore, the correct answer is the option D.
We know that a=100º.
Since(1) b = 30
b+a+f=180º
then we have
30º+100º+f=180º -------------> f=50º.
Since f and c are opposite angles by the vertex then f=c=50º. SUFFICIENT.
Again, since f and c are opposite angles by the vertex then f=c=50º. SUFFICIENT.(2) f = 50
Therefore, the correct answer is the option D.
