This is the process I would use:
Maddy's = 2x 2x+x=15
Meg's = x 3x=15
x=5
Since Maddy's is 2x, multiply the 5 times 2 and you find that Maddy has 10 stickers.

The angles are adjacent because they have a common side and vertex. Basically, they are both right next to each other.
x = 28
Step-by-step explanation:
When (x + 6)° and 56° are added together, they need to equal 90° since they are both parts of a right angle.
(x + 6) + 56 = 90
x + 62 = 90
x = 28
