Answer:

Option B

False

Step-by-step explanation:

False, because

The sum of the exterior angles for each polygon is consistent for all types of polygons whether they are regular or irregular- no matter how many sides is always 360 degree.

for example:

Take any polygon, call it a square and show that a exterior angle of a square is 360 degree.

An exterior angle is formed by a side of the square and an extension of an adjacent side as shown below in the figure.

Let a, b, c and x are exterior angles.

We know that each interior angle in a square is equal to 90 degrees.

Interior angle + adjacent angle = 180°

90°+ x= 180°

or

x = 180°-90° = 90°

Since there are 4 exterior angles

therefore, 4 \times 90^{\circ} = 360°

Therefore, the sum of the exterior angle of a square is 360°

I don’t know how to necessarily complete the tables but i know they are equivalent

1. 3(x-5)
3 (x) = 3x
3 (-5) = -15

that is the distributive property thus it equals

3x - 15

2. 3x - 15

they’re the same

Which value is closest to the perimeter of the window
Eddi Din [679]

Answer:

9.82 feet

Step-by-step explanation:

the perimeter of the window is the circumference of a semi-circle with a diameter of 5

P = (πd)/2     (divided in half because it's only half a circle)

P ≈ 3.14(3.5) which is approx 11

11 is closest to 9.82
