Ineed with "equation practice with angles geometry" problem.

Step-by-step explanation:

The identical arc symbols on the two angles indicates the angles are congruent. Also, these are alternate interior angles where a transversal crosses lines marked as parallel, so they are congruent:

  ∠A = ∠B

  8x +78° = 2x +114° . . . . . substitute the given expressions

  6x = 36° . . . . . . . . . . . . . subtract 2x+78° from both sides

  x = 6° . . . . . . divide by 6

  ∠B = 2x +114° = 2·6° +114° . . . . . put the value of x into the expression

  ∠B = 126°

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.

what are ur choices?
