The tenth place will be the number right after the decimal "." You have to look at the number behind the 7 to see if the 7 will stay at 7 or if it will round up to 8. Since 5 means you round up, you round the 7 to an 8, giving you:
3.8
1021 / 5 = 204.20.....each girl got 204 stickers.....with a remainder of 1 sticker

Answer: x = 45</h3>
Work Shown:
x+x+90 = 180 .... all three angles of a triangle add to 180
2x+90 = 180
2x = 180-90
2x = 90
x = 90/2
x = 45
This is a 45-45-90 right triangle. We also consider it an isosceles right triangle because the base angles (45) are equal.
