The Founding Fathers declared their independence with an important document

The Founding Fathers declared their independence with an important document.

Explanation:

This is the main reason why the Founding Fathers of the United States are easy to identify. The Founding Fathers of the United States wrote a document that marked the establishment of the new country. This document was the Declaration of Independence. This text was not only significant because it marked the end of English government in the colonies. It was also important because it marked the beginning of the new country of the United States.

sin x  = opposite side / hypotenuse  (the hypotenuse is the longest side ) so sin A in the given triangle = 5 / 13

cos x = adjacent side / hypotenuse.  The adjacent side to angle A is AC  so cos A = AC / 13

tan x = opposite side / adjacent side  In the diagram tan A =  5 / AC

csc x = 1 / sin x  = H / O     ( H=hypotenuse and O = opposite) side

sec x = 1 / cos x = H/ A    ( A = adjacent side)

cot x  = 1 / tanx =  A / O

In the triangle   AC^2 = 13^2 - 5^2 = 144 so AC = 12  ( By Pythagoras)
