First option is correct.
Since we have given that
JKL is a right triangle.
Length of JK = 12
Length of KL = 5
By Pythagoras theorem, we get that
So, cos (L) would be
cos(L)=base/hypotenuse
cos(L)=5/13
Hence, First option is correct.

Answer:
A) JK and LM will be parallel to each other.
Step-by-step explanation:
On reflection on line the x co-ordinate changes with y co-ordinate and y co-ordinate changes with x co-ordinate
Points on line EF
On reflection of this line on the new points we get for line JK are
Points on line GH
On reflection on y=x line the new points we get for line LM are
Slope of line JK
Slope of line LM
For two line to be parallel, their slopes will be same.
Since slopes of lines JK and LM are same therefore we can say that these are parallel to each other.
