Answer:

The scale factor for the dilation is 3.

Step-by-step explanation:

We are given that,

Rectangle ABCD is dilated to form the rectangle A'B'C'D'.

<em>To find the scale factor, we will find the ratio of the lengths of the rectangle.</em>

We see that,

A= (1,5) and B= (4,5). So, the length of side AB = 4-1 = 3

A'= (3,15) and B'= (12,15). So, the length of side A'B' = 12-3 = 9

So, the ratio of the sides AB : A'B' = 3 : 9 = 1 : 3.

Hence, we get that,

<em>Length of side A'B' is 3 times the length of side AB.</em>

This relation can be verified for other sides also.

Thus, the scale factor for the dilation is 3.

Answer:   x = -1

Step-by-step explanation:

x + 5 - 4x = 8

-3x + 5 = 8

-3x = 8 - 5

-3x = 3

-3x/3 = 3/3

-x = 1

x = -1

What is the measure of each angle of the hexagon? 60° 90° 120° 144°
Veseljchak [2.6K]

Answer:

120

Step-by-step explanation:

A hexagon has six sides, and we can use the formula degrees = (# of sides – 2) * 180. Then degrees = (6 – 2) * 180 = 720 degrees. Each angle is 720/6 = 120 degrees.
