Answer:
x = ≈4.78
Step-by-step explanation:
25.1226x / 7.85 = 15.3
25.1226x = 15.3 × 7.85
25.1226x = 120.105
divise by 25.1226 to isolate x
x = ≈ 4.78
General Idea:
The measure of one of the central angles of a regular Polygon () can be used using the below formula:
Applying the concept:
The measure of one of the central angles of a regular octagon.
The octagon have 8 sides, using the above formula we get...
Conclusion:
The correct option is <em><u>A) 45 degrees</u></em>
Option D x = -8 is correct option.
Step-by-step explanation:
We need to solve the inequality:
Solving:
All the values less than 7 are included in the number line.
The graph on number line is shown in figure attached.
In the options given, all values in Option A, B and C are greater than 7 so these cannot be included.
while Option D is less than 7 so, x=-8 is correct
Option D is correct.
