What kinds of regular polygons can be used for regular tesselations
Ahat [919]
To tessellate a surface using a regular polygon, the interior angle must be a sub-multiple (i.e. factor) of 360 degrees to cover completely the surface.

For a regular three-sided polygon, the interior angle is (180-360/3)=60 °
       Since 6*60=360, so a regular three-sided polygon (equilateral triangle)            tessellates.
For a regular four-sided polygon, the interior angle is (180-360/4)=90 °
       Since 4*90=360, so a regular four-sided polygon (square) tessellates.
For a regular five-sided polygon, the interior angle is (180-360/5)=108 °
       Since 360/108=3.33... (not an integer), so a regular five-sided polygon           (pentagon) does NOT tessellate.
For a regular six-sided polygon, the interior angle is (180-360/6)=120 °
       Since 3*120=360, so a regular six-sided polygon (hexagon) tessellates.

BRAINLIESTTT ASAP! PLEASE HELP ME :)<br> thanks!
Fynjy0 [20]

The answer is [ yes; ΔABC ~ ΔFGH by SAS Similarity ]

SAS Similarity states that two triangles have congruent corresponding angles and the corresponding sides have an identical ratio

The angle measure aren't given but the angles look to be the same.

To find the scale factor, divide.

12 / 8 = 1.5

15 / 10 = 1.5

The corresponding sides have an identical ratio.

This proves that option B is correct.

Best of Luck!

At a certain real estate firm, realtors selling homes receive a commission of: 7% for the first $100,000 of the selling price, a
scoray [572]

Answer: The actual price of house sold at $109000.

Step-by-step explanation:

Since we have given that

Selling price = $100000

Rate of commission = 7%

So, Amount of commission would be

\dfrac{7}{100}\times 100000\\\\\=\$7000

Total commission = $7540

So, Remaining amount of commission would be

\$7540-\$7000\\\\=\$540

Rate of commission exceeding $100000 = 6%

Let the selling price of house be 'x'.

According to question,

\dfrac{6}{100}\times x=540\\\\0.06x=540\\\\x=\dfrac{540}{0.06}\\\\x=\$9000

Hence, the actual price of house sold at

$100000+$9000=$109000.
