Answer:

1. use the formula

$(n-2)180$

$(20 - 2)180\\18 * 180 = 3240$

2. use the formula

$360/n\\360/12\\n = 30$

3. There is only one at 360 degrees

4. there are 6 rotational symmetries and the number of reflectional symmetries would be 6 as you can see:

docker41 [41]

Area of wooden support is 36 square inches

Solution:

Given that, carpenter cut out a small trapezoid as a wooden support for the front step

The area of trapezoid is given as:

$area = \frac{a+b}{2} \times h$

Where, "h" is the height

"a" and 'b" are the length of base

Here given that,

Height = h = 4 inches

a = 6 inches

b = 12 inches

Substituting the values we get,

$area = \frac{6+12}{2} \times 4\\\\area = 18 \times 2\\\\area = 36$

Thus area of wooden support is 36 square inches
