Question 1175765
.


In your post, the object  " L "  is not defined;


the objects  " E "  and  " H "  are not defined,  too.


We do not see the Figure - - - therefore,  we can not know what the objects  LA,  AE  and  AH  are.


These are the reasons,  why we can not solve this problem.



By the way, even although you can not present the Figure in the post,

you still should be able to describe the situation, using your own words . . .
