Answer: First option is correct.
Step-by-step explanation:
Since we have given that
JKL is a right triangle.
Length of JK = 12
Length of KL = 5
By pythagorus theorem, we get that
[tex]JK^2+KL^2=JL^2\\\\12^2+5^2=JL^2\\\\144+25=JL^2\\\\169=JL^2\\\\JL=\sqrt{169}\\\\JL=13[/tex]
So, cos (L) would be
[tex]\dfrac{Base}{Hyptonuse}=\dfrac{5}{13}[/tex]
Hence, First option is correct.
