Answer:

x° = 125°

(x+10)° = 135°

Step-by-step explanation:

<u>Given:</u>

Sum of measures of angle = 720°

<u>Solution:</u>

We know that:

Sum of measures of angle = 720°

120 + 100 + 120 + x + 10 + 120 + x = 720

x + x + 120 + 100 + 120 + 10 + 120 = 720

2x + 470 = 720

2x = 720 - 470

2x = 250

Divide both sides by 2

x = 250/2

x = 125

Now,

<u>Angles measures</u>

x° = 125°

(x+10)° = (125+10)° = 135°

$\rule[225]{225}{2}$

Hope this helped!

Answer:

120+100+120+120+x+x+10=720 (given)

470+2x=720

2x=720-470

x=250/2

x=125

The function h(x) is a transformation of the square root parent function,

kondaur [170]

Answer:

A. $h(x)=\sqrt{x-3}$

Step-by-step explanation:

<h3>Step 1: Definition</h3>

The parent function of $\sqrt{x}$ is translated to the left when $h$ is positive in the transformation $\sqrt{x+h}$ .

If $h$ is negative, the graph translates towards the left with the distance equal to the value of $h$ .

<h3>Step 2: Implementation</h3>

Here the graph moved 3 units towards the right. This means that $h$ is negative and has the value of 3.

So, plugging that into the parent function for translation, the function becomes:

$h(x)=\sqrt{x-3}$

Population management is essential for development justify the statement

olya-2409 [2.1K]

Answer:

Population management is important due to the fact that humans rely on different types of animals for food that if we populate to much that we could all run out of food because say if there are 30 humans and 5 pigs even if they both multiply there well still not be enough in the long run. Which throws the balance over nature off. So if we keep on populating we are practically killing are selves, population management is essential if you do not want the human race to die out.

Kelly drew a circle with a diameter of 8cm Paige drew a circle with a radius of 3cm approximately how much larger is the area of

nlexa [21]

Answer:

15.7

Step-by-step explanation:

d = 2r

d = 8 thus r = 4

area (kelly) = 4 x4 x $\pi$ = 16 $\pi$

area (paige) = 3 x 3 x $\pi$ = 9 $\pi$

difference = 16 $\pi$ - 9 $\pi$ = 5 $\pi$ = 15.7
