Does anyone know how to do this I’m really confused

<h3>Given:</h3>

Pentagon

The size of the unknown angle "x"

<h3>Solution:</h3>

The given polygon is a Pentagon so the sum of interior angle will be,

$\large\boxed{Formula: ( n − 2 ) × 180}$

n means the number of sides

Let's substitute the values according to the formula.

$(5-2)×180$

$=540°$

Now, we can find the sum of one interior angle.

$\large\boxed{\frac{sum \: of \: interior \: angles}{n}}$

n means the number of sides.

Let's substitute the values according to the formula.

$x=\frac{540}{5}$

$\large\boxed{x= 108°}$

Therefore, the size of the unknown angle "x" is 108°

Integrate (x^3)/(a^2)-(x^2) ?

notka56 [123]

Hi!

$\frac{x^3}{(a^2)-(x^2)}$

First remove parenthesis.

$\frac{x^3}{a^2-x^2}$

Factor $a^2-x^2$ or $(x+a)(a-x)$

$=\frac{x^3}{(a+x)(a-x)}$

Hope this helps! Thank you for posting your question at here on Brainly. Have a great day.
