An n-sided polygon has two of its exterior angles measuring 30° and 42°.The remaining exterior angles all measure 16° each. Find the value ot n.

Answers

Answer:

n = 20.

Step-by-step explanation:

The external angles of a polygon add up to 360 degrees. So:

30 + 42 + 16(n - 2) = 360 where n is the number of sides of the polygon.

16n + 30 + 42 - 32 = 360

16n + 40 = 360

16n = 320

n = 20.

What is the length side of a triangle that has vertices at (-5, -1), (-5, 5), and (3, -1)?

Answers

Answer: 6,8 and 10

Step-by-step explanation:

To find the length , all we need to find is the distance between each point ,

the formula for calculating distance between two points is given by :

D = $\sqrt{(x_(2)-x_(1)) ^(2)+(y_(2)-y_(1)) ^(2)}$

Let the points be :

A ( -5,-1)

B(-5,5)

C(3,-1)

Calculating the length AB , we have

D1 = $\sqrt{(x_(2)-x_(1)) ^(2)+(y_(2)-y_(1)) ^(2)}$

D1 = $\sqrt{(-5+5)^(2)+(5+1)^(2)}$

D1 = $√(36)$

D1= 6

Calculating the length AC , we have

D2 = $\sqrt{(x_(2)-x_(1)) ^(2)+(y_(2)-y_(1)) ^(2)}$

D2 = $\sqrt{(3+5)^(2)+(-1+1)^(2)}$

D2 = $√(64)$

D2 = 8

Calculating the length BC , we have

D3 = $\sqrt{(x_(2)-x_(1)) ^(2)+(y_(2)-y_(1)) ^(2)}$

D3 = $\sqrt{(3+5)^(2)+(-1-5)^(2)}$

D3 = $√(100)$

D3 = 10

Therefore ,the length of the sides of the triangle are 6,8 and 10

Find the area of the circle. Use 3.14 for pi. The diameter is 36 ft

Answers

Answer: 113.04

Step-by-step explanation:

To find the area you have to do diameter x 3.14 as pi

36 x 3.14 = 113.04

You can only draw one unique isosceles triangle that contains an angle of 55°?

Answers

-- If the 55° angle is one of the two equal angles, then
the third angle is 70° .

-- If the 55° angle is the third angle, then each of the two
equal angles is 62.5° .

-- For either of these cases, there are an infinite number
of possible sets of side-lengths.

Eight friends share 2 pizzas equally. How much pizza does each friend get

Answers

It depends on how much slices you split it into if it is the traditional 8 then there is 16 slices and 8 people divide each by 8 to get every person gets 2. Hope this helps.

It depends on how many slices the pizzas are cut into. Usually a pizza is cut into 8 slices. If there are 8 friends and 16 slices that means each friend gets 2 peices.
