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.

The data frames is the sorting of data into small frames and clearing out raw data which makes the data important for the user. The input values are inserted by the user as the statement and the statements are interpreted as the values and the results are shown.
Answer:

Step-by-step explanation:
Since Segment BOA is a diameter:

Arc Ac and Arc CB are in a ratio of two to four. Since Segment BOA is a diameter, Arc ACB measures 180°. Letting the unknown value be <em>x</em>, we can write that:

Hence:

Thus, Arc CB = 120°. By the Inscribed Angle Theorem:

Therefore, ΔABC is a 30-60-90 triangle. Its sides are in the ratios shown in the image below.
Since AC is opposite from the 30° triangle, let AC = <em>a</em>.
We are given that AC = 9. Hence, <em>a</em> = 9.
BC is opposite from the 60° angle and it is given by <em>a</em>√3. Therefore:
