The polygon shown is a pentagon, a five-sided polygon.

There is a formula to find the sum of the measures of the interior angles of any polygon.

S = (n - 2)180

S = sum of the measures of the interior angles

n = number of sides

This is a pentagon, so it has 5 sides. n = 5

We can find the sum, S, of the measures of the angles of any pentagon.

S = (n - 2)180

S = (5 - 2)180

S = 3(180)

S = 540

The sum of the measures of the interior angles of a pentagon is 540 deg.

Now we add all the measures that are shown and subtract from the sum of the measures. That will give us the measure x.

104 + 117 + 100 + 124 = 445

540 - 445 = 95

x = 95

x = 95°

the polygon has 5 sides so you do n - 2 which is (number of sides - 2) this gives us 3. now multiply 3 times 180, this gives us 540. now add up all the sides that you know, 104, 117, 100, 124, this is 445 now subract 445 from 540 and that is what gives us 95°

What is the domain of the function?<br><br> y= sqrt 5x-10

Andrews [41]

I don't know if this will help but I found this on YAHOO!

Answer: Domain of definition of a function is the set of numbers which the variable attains and for which the function is defined.

Step-by-step explanation:

f(x) = sqrt (5x-10)

Here x can have value equal to any real number >=2 because if x attains value less that 2, 5x-10 becomes negative and sqrt(5x-10) has no real value.

therefore the domain of the function f(x) is (2, infinity) inclusive of 2.

Answer:

2 50-pound bags

Step-by-step explanation:

[Conversions] 50-pound bags -> 800-ounce bags

[Total potatoes used] 200 mashed potato creations * 8 ounces of potatoes in each dish = 1,600 ounces of potatoes

[Bags used] 1,600 / 800 = 2 bags

Answer:

$AC=\sqrt{13}$

Step-by-step explanation:

As the the length of the segments BC = AC, so the triangle ABC must be an isosceles triangle.

As CD ⊥ AB, it means the base AB gets bisected by CD, making two congruent angles named as ∠ACD and ∠BCD. As shown in attached figure.

CD bisecting the base AB into two equal parts means if AB = 4, then

the length of AD = 2 and the length of DB = 2. Hence, AD = DB

As BC = AC, it means these two equal sides of isosceles triangle would make equal angles on the opposite side. Hence, angle ∠A and ∠B would be equal as shown in attached figure.

As CD is bisecting the base AB into two equal parts. Hence, it can be treated as the part of two right triangles named ACD and BCD.

So, the length of AC can be easily determined using using the Pythagoras formula.

So,

c² = a² + b²

$c=\sqrt{a^{2}+b^{2}}$
