Identify ONE way that technological changes facilitated trade in the Indian Ocean in the period 1200–1450.

The technological invention of the magnetic compass helped facilitate the Indian ocean trade between 1200-1450.

The magnetic compass helped a great deal in navigation while sailing on the Indian ocean, the Atlantic ocean as well as across Africa.

The magnetic compass helped merchants to travel easily across different locations. The magnetic compass served as a guide to sailors as it pointed them to different locations they needed to go for trades.

Explanation:

The compass played a vital role in navigating through seas and oceans. It was one of the Chinese technological inventions that changed the Indian Ocean trade from 1200 to 1450. During this period, the trade carried between the Han dynasty, the Maurya Empire, and the eastern coast of Africa. The Chinese dominated the trade, and introduce massive trading ships called Junks which were able to carry cargoes. Junks used for fishing, trading, and exploring the seas and oceans in Asia because they were easy to manoeuvre and stand in rough water.  

he believed that strong monarchies would lead to social and political stability.

the perimeter of a triangle is 69 cm. side a is 5 cm shorter than side b. side c is twice as long as side a. find the length of each side. i need to know how to do it in 2 equations.  

equations:

a = b-5

c = 2a

a + b + c = 69
