- Which of the following is most likely the next step in the series ?
- The next series is most probably going to be <u>option </u><u>D.</u><u> </u>
- We can see from the series that, figure 1 has 4 points marked on the circle from which they formed a rectangle.
- In the next figure, there are 3 points marked which together when joined forms a triangle.
- Then the next circle has 2 points marked on it which makes a straight line.
- So, obviously the next figure/circle in the series should have only 1 point marked on it. This won't form anything as you can't join just 1 point with something.

Answer:
C) 14 cm
Step-by-step explanation:
A triangle solver can quickly show you the third side is 14 cm.
__
The law of cosines can be used for this purpose. If the given sides are 'a' and 'b', and the third side is 'c', then that law tells you ...
c² = a² +b² -2ab·cos(C)
c² = 7² +11² -2·7·11·cos(100°) ≈ 196.74
c ≈ √196.74 ≈ 14.03
The length of the third side is about 14 cm.
