Giving the right triangle JKL what is the value of cos (L)
kvasek [131]
<h2><u>Answer:</u></h2>

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

Which of the following statements is correct?
patriot [66]

Answer:

B) Distinctly alkaline diagnostic horizons, thin profiles, lack of organic material, and dominance of sandy materials are features most closely associated with aridisols.

Explanation:

The aridisols are types of soils that are found predominantly in arid areas. They are soils that are not considered as fertile, and are near the bottom by quality of soils. These soils are lacking organic material, and also are very exposed to erosion, with the primary reason being the climate, as it doesn't allow for lot of vegetation to grow. The horizons of the aridisols are distinctly alkaline diagnostic ones, with the profiles being very thin and labile. The top layer of the soil is dominated by sandy material, which is a result of the extensive weathering and erosion in their surroundings, so the wind is mostly transporting small sandy grains and covers most of the area with them.
