Circle x is shown in the diagram. Which equation can be used to solve for m∠1? m∠1 = (a – b) m∠1 = (a + b) m∠1 = (c – d) m∠1 = (c + d).

Iwas in a argument about a certain class grade with my teacher. it was a ‘a-’when i felt that i deserved a ‘a’. i showed him (my teacher) why i felt i derserved so. i questioned what i got wrong and showed him what i learned. i look back to that teacher with nothing but love and support because that’s the class that i actually learned the most. the moral of the story is to see where the other person is coming from and what they have done. also, when in a conflict, never attack the persons character. this will just make the argument end poorly.
