Answer:
Hypotenuse x = 30 unit
Explanation:
Given:
Base = 15√2
Perpendicular = 15√2
Find:
Hypotenuse x
Computation:
Hypotenuse x = √Base² + Perpendicular²
Hypotenuse x = √(15√2)² + (15√2)²
Hypotenuse x = √450 + 450
Hypotenuse x = √900
Hypotenuse x = 30
The Marshall Plan
The "Marshall Plan" was named after the man who then was US Secretary of State, George C. Marshall. Officially the plan was called the European Recovery Program. Marshall announced the plan in 1947, and it went into effect in 1948. The intent was to provide aid and rebuilding to European economies after the damaging effects of World War II. The US intended to build up its allies in Europe and stave off communism.
This is a personal question, which means that only you can answer it. However, I can give some examples that might help guide your work.
An example of a primary source that you might encounter in your own life is that of a news article. As this article is likely to be written by a reporter witnessing the events, it can be considered a primary source. On the other hand, an example of a secondary source would be a non-fiction book that talks about a historical event. This is because such a book would give a second-hand account of an event based on historical information.
