Do the 12th and 13th one

Step-by-step explanation:

Important note about this question

The diagram above shows a lot of angles

There is corresponding angles which is called the F angles and corresponding angles are equal

There is also alternative angle which is called the Z angles and alternative angles are also equal.

There is also vertically opposite angles which are also equals

Sum of angle at a point is 360°

Sum of angle on a straight line is 180°

11. To get angle angle "a" is vertically opposite to the 55°

Then, a=55°

Sum of angle "a" and "d" form a supplementary angle

Then a+d=180

Then, d=180-a

d=180-55

d=125°

c and d also makes a supplementary angles

c+d=180

c=180-d

c=180-125

c=55°

Also, c and b form complimentary angle

Then c+b=180

b=180-c

b=180-55

b=125°

c=d=55°, a=b=125°

13. Simple interest is given as

S.I=PRT/100

Where,

S.I is simple interest

P is the principal

R is the rate in %

And T is the time in years

Given that

S.I=?

T=2years

R=6%

Amount =Rs 5000

Note, Amount = P+S.I

5000=P+S.I

Then make P subject of formula

P=5000-S.I

S.I=PRT/100

S.I=(5000-S.I)×6×2/100

Cross multiple by 100

100S.I=(5000-S.I)12

100S.I=60,000-12S.I

100S.I+12S.I=60,000

112S.I=60,000

S.I=60,000/112

S.I= Rs 535.714

Then, the simple interest is

Rs 535.7

the clues that signal the reader should change tone are the punctuation marks, the grammatical signs. for example, the quotation marks at the beginning of something someone else said literally or the exclamation marks.

the tone of the first line of dialogue until "gettysburg" is a kind tone, a tone of advise. the narrator is trying to the other person in doing something he or she obviously is finding hard to do by giving a piece of advise and bringing up a memory of a successful similar case.

the clue that the reader understand how to read the word "bang" is the exclamation mark. it gives the word a surprise tone, a strong accent.

the best tone for reading the word "bang" is an exciting tone, a surprise one, even a loud one.

the words that should be read with a formal tone are the ones that give factual information. the sentence: mister lincoln couldn't think of anything to say at the gettysburg" gives information about an event and it needs to be read formally, also, when the narrator wants to transmit calmness, a formal and slow tone is needed, because people also transmit messages with the vibrations of our voices and tones.

the central idea is that:

individuals should refuse to cooperate with institutions they believe unjust.

thoreau felt  that governments were more often agents of corruption than justice, even democracies, and that just because the majority feels a certain way does not make it just or correct in absolute terms. he uses the fact that slavery exists in our democracy to support this idea.

he goes on to say that, as a result, people should live true to their own internal laws regarding right and wrong, as a product of reflection and a moral life, rather than following every law that society imposes.
