6=68 and 8=112
This is Bc 1=112 and 1 and 4 are virtual angles so 4 would also equal 112. And 4 and 6 are supplementary angles, and supplementary angles always add up to 180, and since 4 is 112 you’d subtract 112 from 180 and you’d get 68, so 6=68 and 6 and 8 are also supplementary angles so 8 would be 112

What is the value of x for this triangle.

Answers

Answer:

13

Step-by-step explanation:

you have to use Pythagorean Theorem which is

(a^2) + (b^2) = (c^2)

where a and be are the legs 45° from each other and c is the hypotenuse.

so just plug in the numbers

5^2 + 12^2 = c^2

25 + 144 = c^2

169 = c^2

now square root both sides to get rid of the square on c

root(169) = root(c^2)

13 = c

Find the value of each variable 17/ 18

Answers

Answer:

A) B.R(-9)?

Step-by-step explanation:

Answer:

17 - 42

18 - 50

Step-by-step explanation:

17)

You know the total measurement of both angles is 180.

So your formula is (2x+54) + x = 180. Now rearrange to get

180 - (2x+54) = x or 180-2x+54 =x

Simply to -2x+126 = x followed by moving x and moving 126 to get

-3x = -126 , now divide both sides by -3

18)

Your complete circle is 360 and  you know one angle is 90.

Set your formula to 360=90+(3x)+(x-20)+(2x-10)

Rewrite to 360 = 90+3x+x-20+2x-10 and combine like terms

360 = 90 - 20 - 10 + 3x + x+2x

360 = 60 + 6x

360 - 60 = 6x

300 = 6x

300/6 = x

50 = x

please help. solve for x. (i’ll give brainles if you help with all!

A cake weighs 215 g and is shared equally between five people. What weight of cake does each person receive?

Answers

Answer: 43 g

Step-by-step explanation: For 215 to be divided equally between five people the equation should be set up as 215/5, which equals 43 g for each person.

You just have to divide the weigh of the cake by the number of people that’ll be sharing it

For example 215g dived by 5 is 43g
Therefore each person receive 43g of the cake.

The least common denominator is  12

=======================================================

Explanation:

Your teacher wants you to list the multiples of each denominator.

The multiples of 3 are: 3, 6, 9, 12, 15The multiples of 4 are: 4, 8, 12, 16, 20

The values in bold are what will go in the boxes in those first two rows.

The least common denominator is 12 because it is the smallest thing found in common in the two lists above. In other words, 12 is the LCM (least common multiple) of 3 and 4. Note how 3*4 = 12. This works because 3 and 4 do not have any common factors between them other than 1.

The LCD (least common denominator) is the LCM of the denominators. The LCD is useful for when you want to add or subtract fractions. The denominators must be the same for you be able to add or subtract them.

C. 2, 808 cm
D. 4,212 cm
E. 8, 424 cm

Answers

Answer:

C. 2, 808 cm^3

Step-by-step explanation:

Given that

The base of the pyramid is 18 centimeters

And, the height of the pyramid is 26 centimeters

We need to find out the volume of the pyramid

As we know that

The volume of the pyramid is

= 1 ÷ 3 × base^2 × height

= 1 ÷3 × 18^2 × 26

= 2,808 centimeter^3

Hence, the correct option is c.

But did you know they are under threat of extinction? That means no more sea otters in the wild and fewer in captivity. Sea otters have been on the Endangered Species List for over 45 years, but there are actions humans can take to protect them.The Fur TradeIn the 1800s, sea otters were hunted for their fur. The fur trade between North America and Europe was booming, and sea otter fur was a popular option because of its thickness. By the mid-20th century, sea otters had been hunted to near extinction. Only 1,0002,000 sea otters were believed to be living in the wild in 1929. Many people thought the species would soon become extinct. However, due to conservation efforts during the second half of the 20th century, sea otter populations recovered. The strengthening of the numbers of sea otters in the wild is often considered to be one of the greatest successes in marine conservation.Despite their comeback, sea otters are sadly still an endangered species. This is due to predators and human impact on the sea otter's habitat.PredatorsSea otters are threatened by other animals in the water and on land. Killer whales are one of the sea otter's main predators now that the seal and sea lion populations are declining. Sharks, sea lions, and eagles also pluck sea otters from the water while bears and coyotes will hunt them on land. Sea otters use their intelligence to outsmart some of their predators. They also use their sharp teeth to protect themselves.What is the author's point of view on the reason the sea otter population recovered?Sea otters learned to eat a more varied diet, saving themselves from extinction.More people started owning sea otters as pets, which increased their number.Laws were passed to shorten the number of months in sea otter hunting season.Conservation efforts in the last half of the twentieth century saved sea otters.
