This assignment has two parts. Part A is a big problem about a ski cabin. You can, and are encouraged to work on this with another student and turn it in a joint work that you both sign. Since it is lengthy, it is important that your work be even more readable and even better organized than usual. Include enough explanation that a person who was not familar with the problem could follow your reasoning.
Problem 6.1 (do this with a partner if you like) Follow this link to the Ski Cabin Problem.
Part B has problems from tests given in 444 in the past.You should find this helpful in your test preparation. For these problems, the usual custom applies. You can consult other students, as usual, but write up your own answers independently.

In this figure, E is on line AC and D is on line AB, and angles
ABC, ACD, and ADE are right angles. Length |AB| = 4 and |AC| = 5
Compute an exact numerical value (i.e., not a decimal approximation) for the lengths of the following segments. Show your reasoning clearly enough to follow, but THIS DOES NOT HAVE TO BE ORGANIZED AND JUSTIFIED AS A FORMAL PROOF; it is problem solving. AD __________ AE __________ |
