If X is another angle, keep in mind that when the figure is a triangle the sum of the angles is 180º (angle1+angle2+angle3=180º) ALWAYS!!
The Canadian Shield refers to the exposed portion of the continental crust underlying North America. The crust, also known as the North American Craton, consists of rock from the Archean and Proterozoic eons and extends from Mexico to Greenland. The Canadian portion runs from central Ontario<span> north to the </span>Arctic Archipelago, and fromLabrador<span> west to the </span>Northwest Territories<span>. The Shield includes some of the oldest rocks on Earth (possibly more than 4 billion years old). While at times a barrier to settlement, the Shield has also yielded great resources, including </span>minerals<span>, </span>coniferous forests<span> and the capacity for</span>hydroelectric<span> developments.</span>

No, I think the orientation was not the same 370 million years ago because 370 millions years ago there is a single super continent is present so with the passage of time, the super continent broken down into seven continents due to the activity of tectonic plates present inside the earth crust. So we can say that the orientation of east coast of United states were not the same 370 million years ago.
Algae and plants lived in shallow seas millions years ago .After dying and sinking to the seafloor, the organic material mixed with other sediments and was buried .Over millions of years under high pressure and high temperature, the remains of these organisms transformed into what we know today as fossil fuels. Coal, natural gas, and petroleum are all fossil fuels that formed under similar conditions.
