Please help. I am not good with this

X= 7

Z= 117

Step-by-step explanation:

Z would be 117 because on the bottom half of the equation it has to be equal to 180. It gave you 63 already and so I just took the 180 and subtracted the 63 to get 117.

z= 117

x= 7

Step-by-step explanation:

Since angle 63 and z are on the same axis, this creates a straight line. And a straight line = 180 degrees. So z can be found by:

180-63= 117

Then x. You can still use the 180 degrees method as well.

180= 117 + (10x-7) (subtract 117 on both sides)

63= 10x-7 (add 7 on both sides)

70= 10x (divide by 10 on each side)

7=x

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.

the answer is 0.071

good luck! : d
