Anthony Drew plans for a triangle porch determine if the triangle can be made justify your response​
garik1379 [7]

The triangle cannot be made.

Solution:

Given sides of a triangle are 8 ft, 20 ft and 8 ft.

<u>To determine if the triangle can be made:</u>

Let us first define the triangle inequality theorem.

Triangle inequality theorem:

The sum of the lengths of the any two sides of a triangle is greater than the length of the third side.

Using this theorem, we can determine if the triangle can be made or not.

8 ft + 20 ft = 28 ft > 8 ft

20 ft + 8 ft = 28 ft > 8 ft

8 ft + 8 ft = 16 ft < 20 ft  

Here the sum of the two sides is less than 20 ft.

This is not satisfy the triangle inequality theorem.

Therefore, the triangle cannot be made.

Find the measure of each interior angle of the regular polygon (The polygon has 12 sides)​
Nostrana [21]

Answer:

150°

Step-by-step explanation:

To find the sum of all the interior angles in a regular polygon, us this formula, where n is the number of sides: (n-2)*180

(12-2)=10

10*180=1800

Now we have the sum of all the angles. But we aren't done yet! We have to divide this value by the number of sides to find the measure of one angle.

So,

1800/12=

150

Hope this helps!
