  1. Does anybody know what a supplement of a number is?

  2. Never mind I looked it up on dictionary.com and it said that it is "the quantity by which an angle or an arc falls short of 180 degrees."

    Basically it means we need to find the angle.

  3. is the solution for 2d correct? I'm just wondering because the question uses 11pi/6 and the solution solves for -11pi/6

  4. For question 6 of exercise 1, it says that the two equal angles are 2Pi/7. Those 2 angles must be complimentary to each other and equal 90 degrees or Pi/2. However added together those angles equal 4Pi/7 which is not complimentary. What is up with this? :)

  5. Oops! i meant to say question 5 of exercise 1. Sorry.

  6. Jessi, ask about that one in class tomorrow.

    Dion, complementary angles don't have to be equal to each other, they just have to sum to pi/2; or 90° but we talk radians now. ;-)

  7. One more question I have. In question 5 of exercise 2 how do we know that y/8 or x/6 is equal to 1/10?? :S
