Answers

Answer:

m∠b=m∠c=61°

Step-by-step explanation:

The 119° angle and ∠b/∠c are supplementary angles. ∠b and ∠c are congruent because they are vertical angles and they are also both supplementary to the 119° angle. I will use b to find c.

[tex]b+119=180[/tex]

[tex]b=61[/tex]

Since b and c are equal, c=61 too.

Answers

Answer:

Step-by-step explanation:

you know some things about the two angles they are the complimentary parts of just one of those perpendicular lines. so you can say

180 = (6x + 5) + (3x+13)

180 = 9x +18

162 = 9x

18 = x

Answer:

Solution given;

6x+5+3x+13=180(sum of exterior angle is 180°)

9x=180-18

x=162/9

x=18 is a required answer.

Answer:

7) 57.8

8) 73.8

Step-by-step explanation:

The tangents from a given point are the same length. This means the perimeter can be calculated as twice the length of one side plus twice the length of an opposite tangent.

7) P = 2(22.2 +6.7) = 57.8

8) P = 2(22.9 +14) = 73.8

what else would you need to measure the area of something

Answers

The simplest (and most commonly used) area calculations are for squares and rectangles. To find the area of a rectangle, multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area.

Both effectively changed the popular opinion about emotional issues for their countries and brought in a wave of change that was long overdue. But the practice of non-violent protest, or civil disobedience, started long before either Gandhi or King. It began with a quiet, shy poet who is best known for writing a lot about a pond.Henry David Thoreau lived from 1817 until 1862, mainly in the area of Concord, Massachusetts. The issue that would tear the country apart in the 1860s had already begun dividing the nation. Thoreau was only 14 when Nat Turner led the slave rebellion in Virginia and was later hanged. In his late 20s, Thoreau began speaking against slavery in public, echoing the voices of freedmen like Frederick Douglass and Lewis Hayden.Thoreau believed that a government that supported slavery was corrupt and immoral. He was also deeply suspicious of government. For these and other reasons, Thoreau refused to pay his poll tax for a number of years. The poll tax was a legal tax owed by every person. It was basically a tax on one's body. After not paying for years, he was at last arrested. He spent only one night in jail, however, as a relative paid the tax for him. He was reportedly furious that any tax was paid on his behalf.It was this experience that Thoreau wrote about in an essay called "Civil Disobedience." In this essay, he argued that being moral and just came before allegiance to government. He wrote If the machine of government is of such a nature that it requires you to be the agent of injustice to another, then, I say, break the law." He also felt that voting was not enough to ensure that the right thing be done. He wrote that "even voting for the right is doing nothing for it A wise man will not leave the right to the mercy of chance" He felt that one had a moral responsibility to resist unjust laws.Review the third paragraph of Part 1:Thoreau believed that a government that supported slavery was corrupt and immoral. He was also deeply suspicious of government. For these and other reasons, Thoreau refused to pay his poll tax for a number of years. The poll tax was a legal tax owed by every person. It was basically a tax on one's body. After not paying for years, he was at last arrested. He spent only one night in jail, however, as a relative paid the tax for him. He was reportedly furious that any tax was paid on his behalf.How does the final sentence in the paragraph show the change in the way Thoreau is described? It emphasizes the strength of his beliefs. It implies he was unpredictable. It suggests he wasn't such a nice man. It suggests he really didn't like jail.
