Answer:
L = a √( 4 + 2√2)
Step-by-step explanation:
L = a √( 4 + 2√2) is the equation which can be used to calculate the length of each side of the octagon. In the equation i.e. L = a √( 4 + 2√2), in which ''a'' is the length of each side of the octagon. So by putting of ''a'' we get the length of each side of the octagon. The octagon is regular means all of its sides and angles are congruent or similar to each other. Each angle in the octagon has a measure of 135 degrees.
Answer:
The scale factor is 4
Step-by-step explanation:
This question requires an attachment; I'll answer this question using the attached figure
From the attachment
<em>Length OA = 3 units</em>
<em>Length OA' = 3 units + 9 units</em>
<em>Length OA' = 12 units </em>
<em></em>
Scale Factor is calculated as follows;
Given that the original shape is ABC, the original side will be OA
Hence, Original Side = 3 units
New Side = OA' = 12 units
The formula becomes
<em>Hence, the scale factor is 4</em>
