Answer:

  • <em>Sum of exterior angles of a polygon is 360°</em>

#8

  • 2x + 2(64°) + 36° + 48° = 360°
  • 2x + 212° = 360°
  • 2x = 360° - 212°
  • 2x = 148°
  • x = 74°

#9

  • x + 73° + 109° + 90° = 360°
  • x + 272° = 360°
  • x = 360° - 272°
  • x = 88°

Naddika [18.5K]

Answer: The road, crucifix/cross, sidewalks, railroads, and so much more.

Step-by-step explanation: Roads are parallel so that everyone can get to the same place in different lanes. This is important because lines that aren't parallel will inevitably meet, meaning that a highway would eventually merge its two lanes. This happens, but most of the highway is parallel. The same is true of sidewalks and railroads. The crucifix/cross is a Christian symbol, and while I'm not Christian, I'm sure it's important to a lot of people who are.
