Question 1192167
.


In your post, who are the points A, B, C, D E and how these points and the angles do relate to the lines m, n, r and s ?


Please keep in mind that we do not have and do not see this diagram, which is announced as shown, but actually is NOT SHOWN.



May I give an advise to you to read what you post and to think on it BEFORE you submit it ?
