5. Which of the following are true statements? Select all that apply. (2 points)
sin 50° = sin 22° cos 28° + cos 22° sin 28°
sin 50° = sin 72° cos 22° - sin 72° cos 220
cos 50º = cos 64º sin 14° + cos 64 sin 14°
tan50° = tan 52°+tan 2°/ 1-tan 52°tan 20
tan50°=tan 11° + tan 39°/ 1-tan 11°tan39°

Step-by-step explanation:

Solving them each

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.

a is the right answer
