Rounded to the nearest 0.01 or

the Hundredths Place would equal 0.00.

so then you do 0.00 ÷ 8 = 0

Hey Hun

since,the sum of all the angles of a triangle=180°

so ...X=180°-(45+55)

X=180-100=80°

Step-by-step explanation:

45+55 +x=180

x=180-100

Answer:

1. DF=GH 2. I'm not sure, sorry 3. I think it is 41.

Step-by-step explanation:

For question one, just find the angles that are similar :).

For 3, I just subtracted the angles, :).

1. DF=GH 2. I'm not sure, sorry 3. I think it is 41. is the answer to the question

Answer:

Complementary Angles: The angle with 32˚ and 48˚

Supplementary Angles: The angle that is together with the angles of 107˚ and 73˚

Neither: The angle with 101˚ and 77˚ since

Step-by-step explanation:

Complementary angles are angles that sum up to 90˚ so 32 plus 48 is 90 which makes it a complementary angle.

Supplementary angles are angles that sum up to 180˚ so 107+73 is 180 which makes it a supplementary angle.

To find the angle with "neither" Complementary nor Supplementary you use the process of elimination

Answer:

£477.5

Step-by-step explanation:

According to the problem, calculation of given data are as follows,

Total jumper bought = 80

Total spends = £130

Now, first sell 75% of jumper for £9 each, then

75% × 80 = 60

So, 60 × £9 = £540

Remaining jumper = 80 - 60 = 20

Selling half of remaining, 20÷ 2 = 10

Selling 10 jumper = (5 × £9) + (5 × £4.5 ) ( buy one get one half price)

Income of 10 = £45 + £22.5 = £67.5

So, total income by selling 70 jumpers = £540 + £67.5 = £607.5

Hence, Profit = £607.5 - £130

= £477.5

length = 9 units

Step-by-step explanation:

l = length

n - 6 = width

A = n(n - 6)

A = n² - 6n

27 = n² - 6n

n² - 6n - 27 = 0

(n + 3)(n - 9) = 0

n = -3, n = 9

length must be 9 because it cannot be a negative value

Answer:

30 bows

Step-by-step explanation:

To find how many bows she can make, divide 10 by 1/3

10 / (1/3)

= 30

So, Sara can make 30 bows

Answer:

30

Step-by-step explanation:

If she needs just one third then she can make three ribbons out of a yard. so you multiply 3 by the number of yards she has so:

3 x 10 = 30

Let's assume the no. of chocolate pastry bought = x

and the no: of fruit pastry bought = y

➣ Cost of 1 chocolate pastry = Rs 26

➣ Cost of x chocolate pastry = Rs 26x

➣ Similarly, cost of fruit pastry = Rs 18 y

➣ It is given that the total cost = Rs 500

Therefore, Rs 26x + Rs 18 y = Rs 500

If we assume x = 4 and y = 22 , then

26 x 4 + 18 X 22 = Rs 500

104 + 396 = 500

⇝ No. of chocolate pastries bought = 4 ✔

⇝ No. of fruit pastries bought = 22 ✔

And we're all done! :D

The missing dimension of the prism is A

because the volume of the rectangular prism equals the product of the sides, we have:

V = (x - 1)(x - 3)A

but V = x³ - 8x² + 19x - 12

=> x³ - 8x² + 19x - 12 = (x - 1 )(x - 3)A

⇔ x²(x - 1) - 7x(x - 1) + 12(x - 1) = (x - 1)(x - 3)A

⇔ (x² - 7x + 12)(x - 1) = (x - 1)(x - 3)A

⇔ (x² - 3x - 4x + 12)(x - 1) = (x - 1)(x - 3)A

⇔ (x - 3)(x - 4)(x - 1) = (x - 1)(x - 3)A

⇒ A = x - 4

Given:

The figure of a triangle.

To find:

The exterior angle of the triangle m∠NPI.

Solution:

According to the exterior angle theorem, value of exterior angle of a triangle is equal to the sum of the opposite interior angles.

Using the exterior angle theorem, we get

[tex]m\angle NPI=65^\circ+78^\circ[/tex]

[tex]m\angle NPI=143^\circ[/tex]

Therefore, the measure of angle NPI is 143 degrees.

[tex]\boxed {\boxed {\sf 3060 \textdegree}}[/tex]

Step-by-step explanation:

The sum of a polygon's interior angles is found using this formula:

[tex]180 \textdegree (n-2)[/tex]

where n is the number of sides. This polygon has 19 sides.

[tex]n=19[/tex]

[tex]180 \textdegree*(19-2)[/tex]

[tex]180 \textdegree*(17)[/tex]

[tex]3060 \textdegree[/tex]

The sum of the interior angles is 3,060 degrees.
