Elden [556K]

The colonists could export goods only to Britain, according to the Navigation Acts.

According to these laws, no goods originating from the English colonies in Asia, Africa or America could be imported or exported by foreign ships.

This meant that foreign ships could not conduct any trade operations in the ports of English overseas possessions, nor transport goods to England, Ireland or Wales.

This increased the price of imported goods, thus causing a great harm to the economy of the Thirteen Colonies.

morpeh [17]

Answer:

Many countries use GDP per capita to compare the quality of life in different countries.

Explanation:

GDP per capita is gross domestic product divided by the number of inhabitants of a country. GDP is the sum of all goods in a country, and the higher the GDP, the more it demonstrates how developed that country is, and can be classified among poor, rich or developing countries.

Per capita GDP is used as an indicator of a country's quality of life, because the richer the country is, the more its citizens benefit. For this reason, we can conclude that many countries use per capita GDP to compare the quality of life of different countries.

Pat needs to determine the height of a tree before cutting it down to be sure that it will not fall on a nearby fence. the angle

Mekhanik [1.2K]

The height of the tree, which Pat needs to determine, before cutting it down to be sure that it will not fall on a nearby fence is 111 ft.

<h3>What is right angle triangle property?</h3>

In a right angle triangle, the ratio of the opposite side to the base side is equal to the tangent angle between them.

$\tan\theta=\dfrac{b}{a}$

Here, (b) is the opposite side, (a) is the base side.

Pat needs to determine the height of a tree before cutting it down to be sure that it will not fall on a nearby fence.

The angle of elevation of the tree from one position on a flat path from the tree is

$H=40^o$

From a second position,

$I=60\rm\; ft$

Farther along this path it is,

$b=30^o$

Let the distance between tree and first position is x. Thus, from the trigonometry,

$\tan 40=\dfrac{h}{x}\\h=x\tan 40$ ....1

The distance between tree and second position is (x+60) ft. Thus, again from the trigonometry,

$\tan 30=\dfrac{h}{x+60}\\h=(x+60)\tan 40$ ......2

Compare the equation 1 and 2,

$x\tan (40)=(x+60)\tan 30\\0.839x=0.577x+34.64\\0.839x-0.577x=34.64\\x=\dfrac{34.64}{0.262}\\x=132.25\rm\; ft$

Put this value in equation 1 as,

$h=(132.25)\times \tan40\\h\approx111\rm\;ft$

Thus, the height of the tree, which Pat needs to determine, before cutting it down to be sure that it will not fall on a nearby fence is 111 ft.
