Its telling me to find x and the measure of each angle

help its telling me to find x and the measure of each angle

Step-by-step explanation:

the sum of the interior angles is 180°

180 : 2 = 5x + 4x

90 = 9x

x = 10

check

5 * 10 + 4 * 10 = 90

the answer is good

now we find the angles

5x + 4x = 90

5 * 10 = 50 °

4 * 10 = 40°

check

50 + 40 = 90°

the answer is good

3=log(n)=2

answer a: product property

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.
