creativ13 [48]

Answer: The answer is true.

Step-by-step explanation:  The given statement is :

" The area of a regular heptagon can be found by breaking the heptagon into seven congruent triangles and then taking the sum of their areas".

We are to check its is true or false.

In the attached figure, a regular heptagon ABCDEFG is drawn. Sine the heptagon is regular, so all its sides are equal and all its angles are also equal. So, we can break the heptagon into seven congruent triangles 1, 2, 3, 4, 5, 6 and 7 taking 'O' as the centre of the heptagon.

Finding the areas of these seven triangles and taking the sum will result in the area of the heptagon ABCDEFG.

Thus, the given statement is "TRUE".

Kayla spent half of her weekly allowance on clothes. To earn more money her parents let her clean the oven for $4. What is her w
marysya [2.9K]
In this question, the first information that we get is that Kayla spent half of her weekly allowance in clothes. On cleaning the oven Kayla gets $4. Finally Kayla is left with $12.
Let us assume that the weekly allowance of Kayla = x
Amount of allowance saved after buying clothes = x/2
 Then we can go for the equation
x/2 + 4 = 12
x + (4 * 2) = 12 * 2
x + 8 = 24
x = 24 -8
   = 16
So we can now see that the weekly allowance of Kayla is $16
