Question 1151182
.


Notice that  NEITHER  wording part of the post,  NOR  its plotting part do not specify the measure of the angle ABC 
and do not declare that this angle is the right angle.


Therefore,  this problem,  as it is worded,  printed,  posted and presented,  is    D E F E C T I V E.

<pre>
    Jim, the first line of your post is


        Angle ABC is 90°.


    Could you please tell me what is a rationale for this your statement ?


    It is not stated in the original post and not declared in the plot accompanying the original post.


    It is why I said that the presented original post is DEFECTIVE.
