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

johnny is seven years older then his little sister. let j represent jonny's age and s represent his sister

Well to find this out you need to make an equation

s+7=j
So for example if Johnny's sister is 15 then Johnny would be 22 because
s(sister's age) +7(number of years difference between their ages)=22(Johnny's age)
