Is it definition of Congruence?
Rectangle:
A = BH
= (18)(4)
= 72
Finding area of square:
72 = 2x
/2 /2
36 = x
Finding perimeter of square using area:
P = √a * 4
= √36 * 4
= 6 * 4
= 24
Therefore the perimeter of the square is 24 inches. I am not sure so sorry for any mistakes.
Answer:
The angle subtended by an arc at the center is double the angle subtended by it at any point on the remaining part of the circle.
Step-by-step explanation:
Let us consider the image attached.
Center of circle be O.
Arc AB subtends the angle
on the circle and
on the center of the circle.
To prove:

Proof:
In
: AO and PO are radius of the circles so AO = PO
And angles opposite to equal sides of a triangle are also equal in a triangle.
So, 
Using external angle property, that external angle is equal to sum of two opposite internal angles of a triangle.

Similarly,
In
: BO and PO are radius of the circles so BO = PO
And angles opposite to equal sides of a triangle are also equal in a triangle.
So, 
Using external angle property, that external angle is equal to sum of two opposite internal angles of a triangle.

Now, we can see that:

Using equations (1) and (2):

Hence, proved.
11 to 25, because if your counting 11 and there's 25 in all, then 11 to 25
Answer:
No mode
Median 7
Step-by-step explanation:
Mode: The mode is the element that occurs most in the data set. In this case, all elements occur only once, so there is no mode.
Median: Arrange the data in an ascending order and the median is the middle value. If the number of values is an even number, the median will be the average of the two middle numbers.
