Kit Treasure
Posted in cross stitch on 01/23/2011 02:24 pm by adminGeometry Homework Questions?
There are 2 problems that i cannot figure out....
1.Follow the treasure map of Captain Zig Zag to see how far the treasure is from the old stump
-From the ol' pirate stump take ye 30 paces east, then 20 paces north, 6 paces west, and then another 25 paces north, and there ye find my treasure
2. Given: Kite KITE with right < 's KIT and KET. KP=9, TP=4
Find: a. IE
b. The perimeter of KITE
Please help!!
sorry, the kite is set up like this:
K
I P E
T
well that didnt work...
thank you sooooo much!
I have this book, too! Geometry for Enjoyment and Challenge, right?
1. Captain Zig Zag takes 36 total paces east and 45 paces north. Use the Pythagorean Theorem to find the length of the hypotenuse.
2. IP (P is a point on IE) is an altitude drawn from the hyp. (KT)
IP^2 = 9*4
IP^2 = 36
IP = 6, so IE = 12 (Triangles congruent)
Because IP is an altitude, you can use the altitude-on-hyp. Theorems to find the lengths of the sides.
KI^2 = 9*13
KI^2 = 117
KI = sqrt(117)
IT^2 = 4*13
IT^2 = 52
IT = sqrt(52) = 2sqrt(13)
Perimeter of KITE = 2sqrt(117) + 4sqrt(13)
