Answer:

AD = 8, DC = 15, m\,\angle A = 112^{\circ}, m\,\angle B = 68^{\circ}, m\,\angle C = 112^{\circ}

Explanation:

If the quadrilateral presented in figure is a parallelogram, then the following conditions are satisfied:

AD = BC (1)

AB = DC (2)

m\,\angle D = m\,\angle B (3)

m\,\angle A = m\,\angle C (4)

m\,\angle A + m\,\angle B = 180^{\circ} (5)

m\,\angle C + m\,\angle D = 180^{\circ} (6)

If we know that m\,\angle D = 68^{\circ}, AB = 15 and BC = 8, then we have the following results:

AD = 8, DC = 15, m\,\angle A = 112^{\circ}, m\,\angle B = 68^{\circ}, m\,\angle C = 112^{\circ}

You would probably be better off with terrorism and chemistry. Those two subjects seem to be a thought provoking project to do. Good Luck!

PLEASE HELP ME!!!!!!!!!!!!What if the United States, Mexico, and Canada took the EU's example and joined to form a North America
icang [17]

The North American Union (NAU) is a theoretical economic and political union of Canada, Mexico, and the United States. The concept is loosely based on the European Union, occasionally including a common currency called the Amero or the North American Dollar. A union of the North American continent, sometimes extending to Central and South America, has been the subject of academic concepts for over a century, as well as becoming a common trope in science fiction. One reason for the difficulty in realizing the concept is that individual developments in each region have failed to prioritize a larger union.

Some form of union has been discussed or proposed in academic, business, and political circles for decades. However, government officials from all three nations say there are no plans to create a North American Union and that no agreement to do so has been signed. The formation of a North American Union has been the subject of various conspiracy theories
