Explain why a regular polygon cannot have an interior angle that is 40°.

Mathematics
1 answer:
Minchanka [31]3 years ago
8 0

Answer:

Explained below.

Step-by-step explanation:

The formula for the interior angle of any regular polygon is given as;

Interior Angle = 180(n - 2)/n

Where n is number of sides

We are told the interior angle is 40°

Thus;

180(n - 2)/n = 40

Cross multiply to get;

180n - 360 = 40n

180n - 40n = 360

140n = 360

n = 360/140

n = 2.57

Number of sides of a regular polygon cannot be in decimal nor can it have less than 3 sides.

Thus, a shape with interior angle of 40 cannot be a polygon.

<h2>Answer:</h2>

Using the distributive property, we can simplify the expression.

4 × 3 = 12

4 × \frac{1}{4} = 1

4 × (-\frac{1}{2}) = -2

Here is the simplified expression:

12 + c - 2d

Please help explanation if possible
Andrej [43]

Answer:

  y -4 = -2(x -(-11))

Step-by-step explanation:

The point slope formula is ...

  y -k = m(x -h) . . . . . line with slope m through point (h, k)

__

So, the boxes in order from left to right are k, m, h.

The problem statement tells you the point is (-11, 4), so h = -11, k = 4. It also tells you the slope is -2, so m = -2.

Putting these numbers in the required order, we have k = 4, m = -2, h = -11 and the equation of the line is ...

  y-\boxed{4}=\boxed{-2}(x-\boxed{-11})

Round to the nearest tenth wa hit is the perimeter of the triangle
klio [65]

Answer:

D. 11.8 cm

Step-by-step explanation:

This triangle is a 30°-60°-90° triangle. There is a shortcut to find the lengths of the sides of a 30°-60°-90° triangle. The longest side is the hypotenuse. The longest side is double the shortest side or, the shortest side is half the longest side. Here the longest side is 5, so the short leg (shortest side) is 2.5

The other shortcut is that the longer leg is the

short leg×sqroot3

Here, the short leg is 2.5, so the long leg is 2.5×sqroot3

Perimeter is all the sides added together.

5 + 2.5+ 2.5×sqrt3

Do the times first.

5 + 2.5 + 4.3

= 11.8
