  • 10
    • 10a - make this drawing, label all known lengths
    • 10b - exact length means use Pythagorean, answers in radical form if not a perfect square
    • 10c - "Decimal approximation of exact value" meas turn your previous answers into decimals.
    • 10c - do the exercise twice: once based on the 30 degree angle, then again based on the 60 degree angle

  • 8 - exact value means simplified radical expression
  • 9 - 9b, solve using your graphing window
  • 10
  • 11
    • "the slope of the awning is 5/12" is the standard way people talk about the pitch of a roof. It mean that for every 5 up the roof is 12 feet long. Thinking about it in the opposite manner, a roof that extends 12 feet horizontally will rise 5 feet vertically.
    • 11a is asking for the length of the awning roof, the hypotenuse.

  • 11 - We have done several problems like this in the past. Remember the process: use numbers to see the pattern, then turn the numbers into variables to create an equation. I will not answer questions regarding this problem until the next class period: figure it out.
