<u>Answer:</u>

x = 14° || each angle has 108°

<u>explanation:</u>

first we need to find the total interior angle of this shape:

formula: ( n - 2 ) * 180 ..............where n is the number of sides

( 5 -2 ) * 180

540°

if all sides in the shape are equal, they must have same angle of 9x -18

5 ( 9x -18 ) = 540°

9x -18° = 108°

9x = 108° + 18°

9x = 126°

x = 14°

So each angle has: 9x - 18

9(14) - 18

108°

K=am+3mx solve for m

Otrada [13]

Assuming the variables are constants, you isolate m. So move am to the left. K-am=emx. Now divide ex. This gives you, m=(K-am/ex)

The difference between two numbers is 7194. If the subtrahend is 12,806, find the minuend.

valentina_108 [34]

<u>Answer:</u> The minuend is 20000

<u>Step-by-step explanation:</u>

To calculate the minuend, we use the equation:

$\text{Subtrahend}=\text{Minuend-Difference}$

We are given:

Difference between the two numbers = 7194

Subtraend = 12806

Putting values in above equation, we get:

$\text{Minuend}=12806+7194\\\\\text{Minuend}=20000$

Hence, the minuend is 20000

What happens to energy during a change of state? Why is it a physical change?

Flura [38]

Answer & Explanation:

Energy is heat. For example, if you boil a cup of water it has more energy than a cup at room temperature. It is considered a physical change because its properties do not change only the state of matter. On the other hand, if wood burns then that is a chemical change because it changes its chemical properties. Please rank as Brainliest if this helps! Thank you!

A line passes through the points (–1, –5) and (4, 5). The point (a, 1) is also on the line.

IgorC [24]

Answer:

a = 2

Step-by-step explanation:

Let's find the equation of the line using the 2 points given.

Let's call -1 as x_1 and -5 as y_1

also, 4 as x_2 and 5 as y_2

The equation of line is :

$y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)$
