9/10 (x + 8) = 18 ugh math hurts my head

Aneli [31]

Use the distributive property.
9/10 (x + 8) = 18
9/10x + 7.2 = 18
9/10x + 7.2 - 7.2 = 18 - 7.2
9/10x = 10.8
9/10x / 9/10 = 10.8 / 9/10
x = 12

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°
