Step-by-step explanation:

<em><u>all sides of a triangle = 180</u></em>

<em><u>all sides of a triangle = 180</u></em>

<em><u>So</u></em><em><u> 2 angle i.e. 90° (right angle) and 30° (given) and let third angle be x</u></em>

<em><u>so equation forms like</u></em>

<em><u>180 = 90+30+x</u></em>

<em><u>1</u></em><em><u>8</u></em><em><u>0</u></em><em><u> </u></em><em><u>=</u></em><em><u>1</u></em><em><u>2</u></em><em><u>0</u></em><em><u>+</u></em><em><u>x</u></em>

<em><u>1</u></em><em><u>8</u></em><em><u>0</u></em><em><u>-</u></em><em><u>1</u></em><em><u>2</u></em><em><u>0</u></em><em><u> </u></em><em><u>=</u></em><em><u>x</u></em>

<em><u>6</u></em><em><u>0</u></em><em><u> </u></em><em><u>=</u></em><em><u>x</u></em>

<em><u>SO</u></em><em><u> </u></em><em><u>THE</u></em><em><u> </u></em><em><u>ANSWER</u></em><em><u> </u></em><em><u>WILL</u></em><em><u> </u></em><em><u>BE</u></em><em><u> </u></em><em><u>6</u></em><em><u>0</u></em><em><u>°</u></em>

<em><u>HOPE</u></em><em><u> </u></em><em><u>IT</u></em><em><u> </u></em><em><u>WILL</u></em><em><u> </u></em><em><u>HELP</u></em><em><u> </u></em><em><u>YOU</u></em><em><u> </u></em><em><u>☺️</u></em>

According to the fundamental Theorem of algebra, which polynomial function has exactly 11 roots?
liraira [26]
<h2>Explanation:</h2><h2></h2>

The Fundamental Theorem of Algebra states the following:

<em>For</em><em> </em><em>any polynomial of degree n we will have n roots.</em>

<em />

So the general form of the equation of a polynomial is:

A \ \mathbf{polynomial \ function} \ of \ x \ with \ degree \ n \ is \ given \ by:\\ \\ f(x)=a_{n}x^{n}+a_{n-1}x^{n-1}+\ldots +a_{2}x^{2}+a_{1}x+a_{0} \\ \\ where \ n \ is \ a \ nonnegative \ integer \ and \ a_{n}, a_{n-1}, \ldots a_{2}, a_{1}, a_{0} \\ with \ a_{n}\neq

Since our polynomial will have exactly 11 roots, then the equation will have the following form:

f(x)=a_{11}x^{11}+a_{10}x^{10}+\ldots +a_{2}x^{2}+a_{1}x+a_{0}

<h2>Answer:</h2><h2 />

If we have two functions f \ and \ g such that f(g(x))=x for every x in the domain of g, and g(f(x))=x for every for every xin  the domain of  f. If we prove this, then g is the invers function of f and denoted by f^{-1}

1. We need to prove whether f(g(x))=x. So:

f(x)=\frac{4}{5}x+1 \\ \\ g(x)=\frac{5x-5}{4} \\ \\ So: \\ \\ f(g(x))=\frac{4}{5}\left(\frac{5x-5}{4})+1 \therefore f(g(x))=\frac{4}{5}\left(\frac{5x-5}{4})+1

\therefore f(g(x))=x-1+1 \\ \\ \boxed{f(g(x))=x}

2. We need to prove whether g(f(x))=x. So:

g(f(x))=\frac{5(\frac{4x}{5}+1)-5}{4} \\ \\ \\ g(f(x))=\frac{4x+5-5}{4} \\ \\ \\ g(f(x))=\frac{4x}{4} \\ \\ \\ g(f(x))=x

Since f(g(x))=g(f(x))=x, then:

f(x) \ and \ g(x) are inverses to each other.
