How many degrees are each angle of a regular 7 sided shape?

Diano4ka-milaya [45]3 years ago
6 0

Answer:


Step-by-step explanation:

Here is a diagram of a seven sided regular polygon. You use this diagram to find out how many degrees total are in the interior of a the heptagon. There are 5 such triangles which means that since each triangle has 180o the total amount of the interior angles must be 5 * 180 = 900

Since there are 7 interior angles, the answer to how large each one of them is is found by

900/7 = 129.57 which is slightly off because it is a rounded error.

In general, the size of the angles  in a  regular polygon

180(n - 2 ) / n

Where n is the number of degrees in each interior angle. For example for an 8 sided figure you would get

180(8 - 2) / 8 = 180 * 6/8 = 133 degrees.

satela [25.4K]

Answer:

68.245

Step-by-step explanation:

total cost = $81.05

10% discount is 10/100× 81.05=8.105

substract 8.105 from 81.05= 72.945

with a 6.5% sales tax

6.5/100× 72.954 = 4.7

72.945-4.7= 68.245 the actual price

lakkis [162]

Answer:

GH = 7\sqrt{2}

Step-by-step explanation:

Using the sine ratio in the right triangle and the exact value

sin45° = \frac{1}{\sqrt{2} }

sin45° = \frac{opposite}{hypotenuse} = \frac{HI}{GH} = \frac{7}{GH} = \frac{1}{\sqrt{2} } ( cross- multiply )

GH = 7\sqrt{2}

sesenic [268]

Answer:

Order of operations was not used correctly, Do what is inside the parenthesis first. So use the distributive property first and not subtraction.

Step-by-step explanation:

6-4(3-6x)+12x

  • 6-12+24x+12x
  • -6+24x+12x
  • -6+36x or 36x-6
