Developed in the 1830s and 1840s by Samuel Morse (1791-1872) and other inventors, the telegraph revolutionized long-distance communication. It worked by transmitting electrical signals over a wire laid between stations.
As the first means of long-distance communication, the telegraph changed the shape of American society. The telegraph expanded the business possibilities and expedited the work of a variety of professions, including bankers, brokers, lawyers, and hotel proprietors.
First, to find the answer, you need to find the cosine of angle e to find x. cosine equals adjacent over hypotenuse cosine(52)= x/27 x= (cosine 52)(27)
