Find x in the given figure.

Option b, 125° is correct answer.

Step-by-step explanation:

In the above figure,

I) angle 4=55°( being corresponding angles)

ii) angle 4 + x=180°(co- interior angles)

55°+x=180°

x=180°-55°

x=125°

It's the 2nd labeled angle from the right end of the upper horizontal line.

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.
