The measure of each interoir angle of a regualr polygon is 144 . how many sides does this polygon have

1 answer:

6 0

Each Interior Angle = 180 - (360 / number of sides)
# of sides = -360 / (Each Interior Angle -180)
# of sides = -360 / (144 -180)
# of sides = -360 / -36
# of sides = 10

13 can someone please explain this

Lady bird [3.3K]

Answer:

Step-by-step explanation:

13).

This is an equilateral triangle.

We see that all 3 angles are equal, so all sides are equal also.

So 2x - 6 = 10

2x = 16

x = 8.

Abe and Ben each have a certain number of dollars. If Abe gives Ben $5 then Abe and Ben will have the same number of dollars. If

A = 5 + B
A + 5 = 2B

Let's get one of the variables on one side.

A = 5 + B
A = 2B - 5

By the transitive property

5 + B = 2B - 5

Solve for B.

5 = B - 5
10 = B

Use 10 = B in an earlier equation to find A.

A = 5 + B
A = 5 + 10
A = 15

Abe has 15$ and Ben has 10$.

Step2247 [10]

Answer:

$A = 297\pi$

Step-by-step explanation:

To solve this problem we need to be familiar with the formula for the surface area of a cone:

$A = \pi r(r + \sqrt{h^2+r^2})$

We are given the length of a side and the diameter, to calculate the radius divide the diameter in half:

$r = \frac{d}{2}\\r = \frac{18}{2}\\r = 9 cm$

To calculate the height of the cone, we must use the Pythagorean Theorem:

$C^2 = A^2 + B^2$

We can treat the side length as the hypotenuse $C$ , the radius as the base $A$ , and solve for height $B$ . Set the expression up like this:

$C^2 = A^2 + B^2\\24^2 = 9^2 + B^2\\B^2 = 24^2 - 9^2\\B = \sqrt{24^2 - 9^2}\\B = \sqrt{576 - 81}\\B = \sqrt{495}\\B \approx 22.25$

Now we can plug into our original formula:

$A = \pi r(r + \sqrt{h^2+r^2})\\A = \pi 9(9+\sqrt{\sqrt{495}^2+9^2}\\A = \pi 9(9+\sqrt{495 + 81}\\A = \pi 9(9+\sqrt{576})\\A = \pi 9(9 + 24)\\A = \pi 9(33)\\A = 297\pi$
