Question 1200752
.


The formulation in this problem is constructed INCORRECTLY.


Traditionally, descriptions in geometric problems go "from the top to the bottom".


The figures are described first, then the descriptions of their elements follow.


So, in the normal description, you should say first that the triangle is a right-angled,
and only after that describe its sides and angles.



All other attempts to builds a description only demonstrate 
that the "problem's creator" is unprofessional Math writer.
