Question

Someone help please I need help!!

Answer 1

24

Explanation:

(2x + 9 )+ (5x + 3) = 180

x = 24

(I just guessed and checked. It was multiple choice so why not?)

Answer 2

hello

Explanation:

adjacent angles are equal to 180 degrees,

`(2x + 9) + (5x + 3) = 180 \\ 8x + 12 = 180 \\ 8x = 180 - 12 \\ 8x = 168 \\ x = (168)/(8) \\ x = 21 \\ \\`

but, for some reason, does not match the answers…

Can the answers be wrong?

or I miscalculated…

i hope it helps have a nice day
