What is the value of x?

Got answer its 8

x = 80°

Step-by-step explanation:

To solve this we just need to know that the sum of the inner sides of a triangle will always give us 180 °

from here we only have to apply a simple formula by adding the sides of the triangle and knowing that the result is 180 and from there clear the value x that we need to find out

70 + 30 + x = 180

x = 180 -30 - 70

x = 80°

es una operación aritmética.

step-by-step explanation:

no se que fórmula requiera, pero te puedo decir que es adición. deberías revisar porque tema vas y ver que fórmulas puedes aplicar.

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.
