Find x. assume that any segment that appears to be tangent is tangent. select one: a. 50 b. 40 c. 60 d. 70

For the given question , we have to use the following formula

And the measurement of two arcs are 100 and 20 respectively. So on plugging it in the formula, we will get

So the value of x is 40 .

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
