Answer:

x = 67°

Step-by-step explanation:

All angles inside a triangle add up to 180 so...

180 - 46 = 134

134 ÷ 2 = 67

Find d for the arithmetic series with S17=-170 and a1=2
Irina18 [472]
So, we know the sum of the first 17 terms is -170, thus S₁₇ = -170, and we also know the first term is 2, well

\bf \textit{ sum of a finite arithmetic sequence}\\\\
S_n=\cfrac{n(a_1+a_n)}{2}\qquad 
\begin{cases}
n=n^{th}\ term\\
a_1=\textit{first term's value}\\
----------\\
n=17\\
S_{17}=-170\\
a_1=2
\end{cases}
\\\\\\
-170=\cfrac{17(2+a_{17})}{2}\implies \cfrac{-170}{17}=\cfrac{(2+a_{17})}{2}
\\\\\\
-10=\cfrac{(2+a_{17})}{2}\implies -20=2+a_{17}\implies -22=a_{17}

well, since the 17th term is that much, let's check what "d" is then anyway,

\bf n^{th}\textit{ term of an arithmetic sequence}\\\\
a_n=a_1+(n-1)d\qquad 
\begin{cases}
n=n^{th}\ term\\
a_1=\textit{first term's value}\\
d=\textit{common difference}\\
----------\\
n=17\\
a_{17}=-22\\
a_1=2
\end{cases}
\\\\\\
-22=2+(17-1)d\implies -22=2+16d\implies -24=16d
\\\\\\
\cfrac{-24}{16}=d\implies -\cfrac{3}{2}=d

Compare learning about functions to learning a new language. How are they similar
kow [346]

Answer: They are similar many ways.

Step-by-step explanation:

1. There is a law that guides both of them. Because each has a strick law.

2. They both need practice. Practice they say makes one perfect. When u practice both of them, you become familiar on how to use them.

3. The brain has to read meaning to either of the two to be able to be able to learn a pattern of learn.

4. Both language and functions are systems. They are made of different parts, language is made up of different words while function is made up of axioms which theorems.

I will give 30 points please don’t mess around. Write an informal proof for why the construction of an equilateral triangle work
Marina86 [1]

Answer:

An equilateral triangle is one with all three sides the same length. It begins with a given line segment which is the length of each side of the desired equilateral triangle. ... It is similar to the 60 degree angle construction, because the interior angles of an equilateral triangle are all 60 degrees.
