How do i know when to add or subtract in an angle equation?

Answer:

Step-by-step explanation:

< ABD = <ABC + < CBD

Substitute in what we are given

87 = 9x-1 + 6x+58

Combine like terms

87 = 15x +57

Subtract 57 from each side

87-57 =15x +57-57

30 = 15x

Divide by 15

30/15 =15x/15

2=x

We want to find <ABC

<ABC = 9x-1

= 9*2-1

=18-1

=17

Answer:

Step-by-step explanation:

25 - 32 = -7 and 18 - 25 = -7

It means an arithmetic sequence with common difference d = -7

$a_n = a_1+d(n-1)\\\\a_1=32\\d=-7\\\\a_n=32+(-7)(n-1)\\\\a_n = 32-7n+7\\\\\underline{a_n=-7n+39}$
