Triangle ABC has a right angle at C. Next, side AB=7m and side CB=4m. Using inverse trigonometric functions, find the degree measures of angle B and angle A.
Answers
Answer:
A = 34.85°
B = 55.15°
Explanation:
From the diagram attached :
Using inverse trigonometry :
Angle A ;
Sin A = opposite / hypotenus
Tan A = 4 /7
Angle A = sin^-1(4 / 7)
Angle A = sin^-1(0.5714285)
A = 34.849904
A = 34.85°
Angle B;
Cos B = Adjacent / hypotenus
Cos B = 4/7
B = Cos^-1(4/7)
B = cos^-1 0.5714285
B = 55.150095
B = 55.15°

Describe one difference between the Soviet Union and the United States during the Cold War.
Then do what why and how...
Answers
the Soviet Union began a slow process of democratization that eventually destabilized Communist control and contributed to the collapse of the Soviet Union.
Not only was the Soviet Union communist, they were totalitarian, meaning all the power was with the rulers. The United States was capitalist which meant that people could own land and businesses and compete for themselves.
hope this is helpful:)
Answer:
1. Regime. The regime maintained itself in political power by means of the secret police, propaganda disseminated through the state-controlled mass media, personality cultism, restriction of free discussion and criticism, the use of mass surveillance, political purges and persecution of specific groups of people.
2.Gorbachev's decision to allow elections with a multi-party system and create a presidency for the Soviet Union began a slow process of democratization that eventually destabilized Communist control and contributed to the collapse of the Soviet Union.
3.These differences between the two countries stemmed from their ideologies. Communism was the ideology followed by the Soviet Union. Originally founded by Karl Marx, it said that everything should be owned by the government and then divided up equally among the people who would then all work for it. Not only was the Soviet Union communist, they were totalitarian, meaning all the power was with the rulers.
The United States was capitalist which meant that people could own land and businesses and compete for themselves. This led to a stark contrast between poor and rich. They were also a democracy, which meant it was the people who had a say by electing rulers.
In the Cold War, the division was between these two sides, and there was very little in between.

Positives -
- There becomes a higher consumption of certain foods and drinks (a boom-time for ice-cream and cold drinks)
- Domestic tourism is having a boon with "stay-cations"
- Measured industrial output rises, hence GDP rises, because of increased use of electricity
Negatives -
- Heatwaves can cause a surge of dry weather. This could lead to Droughts and could have a negative impact on locals. Crops for farmers could dry out, and there could become a lack of vegetation (for animals too).
- Higher death rate for people with certain conditions (e.g. more heart attacks, especially among-st elderly people)
- Reduced numbers for certain forms of entertainment (ie cinema etc)
