A circle has a circumference of 12. It has an arc of length 8/5. What is the central angle of the arc in degrees?

The angle at the center is 48°

Step-by-step explanation:

Circumference=12

Length of arc=8/5

length of arc=¤/360 x circumference

8/5=¤/360 x 12

1.6=¤/30

Cross product

¤=1.6 x 30

¤=48

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be
