X = 12

Step-by-step explanation:

This is quite simple!

Those two angles MUST add up to 180° since it is a straight angle.

Therefore, you can set them equal to 180°

54° + 10x + 6° = 180°

60° + 10x = 180°

-60°             -60°

10x = 120°

10x/10 = 120/10

X = 12

Hope this helps! :)

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3
