For the right triangle to be given in name of three letters such as this, the right angle is most likely to be in the center, in this case letter K. To determine the common trigonometric properties of a certain angle we may use of the mnemonics SOH - CAH - TOA. 
                          sin angle = opposite side / hypotenuse
                          cosine angle = adjacent side / hypotenuse
                          tangent angle = opposite side / adjacent side
If we let small letter j, k, and l be the sides opposite to angles J, K, and L, respectively. Then, the cos (L) will be,
                                       cos (L) = j/k
 
        
        
        
Latitude is the angular distance of a place north or south of the earth's equator, or of a celestial object north or south of the celestial equator, usually expressed in degrees and minutes. and it is horizontal
        
                    
             
        
        
        
Answer: "Over the last 50 years, while energy consumption grew substantially, the world undertook a transition in its usage of fossil fuels, from solids (coal) to liquids (oil) to gases (natural gas)." "Meanwhile, the share of oil declined as well, from 40% of energy consumption in 1965 to 33% in 2016."
