 <span>Let x denote the length of the shorter leg. Then the longer leg has length 2x. The hypotenuse of the triangle has length √(x² + (2x)²) = √5 x. 

The cosine of the angle formed by the longer leg and the hypotenuse is 2x/(√5 x) = 2/√5 = 2√5 / 5 

The cosine of the other acute angle is x/(&radc;5 x) = 1/√5 = √5 / 5</span>

Why were americans susceptible to fear based politics in the early 1950s?
Serga [27]
Revelations that spies in the US atomic program had passed secrets to the Soviet Union set off a nationwide panic that communist spies might be infiltrating many American institutions.
Allegations that Hollywood was rife with communists led the House Committee on Un-American Activities (HUAC) to investigate many actors, writers, and directors during the 1950s. Alleged communists were placed on a blacklist and barred from working in Hollywood.
Republican Senator Joseph McCarthy took advantage of this widespread paranoia to advance himself politically by accusing State Department employees of communist leanings. McCarthy's accusations were unsubstantiated, and the Senate eventually censured him.

How did the internal conflicts that the us faced lead to a new government?
lapo4ka [179]

During the 1790s, the young republic faced many of the same problems that confronted the newly independent nations of Africa and Asia in the 20th century. Like other nations born in anti-colonial revolutions, the United States faced the challenge of building a sound economy, preserving national independence, and creating a stable political system which provided a legitimate place for opposition.In 1790, it was not at all obvious that the Union would long survive. George Washington thought that the new government would not last 20 years. One challenge was to consolidate public support. Only about 5 percent of adult white males had voted to ratify the new Constitution and two states, North Carolina and Rhode Island, continued to support the Articles of Confederation. Vermont threatened to join Canada.

What term doesn't belong : Kubali Khan, Great Khan, Yuan Dynasty, Tamerlane
larisa [96]

Answer: Yuan Dynasty

Explanation:

Yuan Dynasty was China's first foreign-led dynasty and it was one of the great dynasties of that time. This is the term that is not belonging here because Tamerlane, Kublaii Khan, and Great Khan were leaders who led their territory and Yuan Dynasty was Dynasty that led China.

The Yuan Dynasty lasted from 1279 to 1368 which is about a hundred years of leadership and that is why this dynasty is also not fiting in these groups of leaders.
