Geocache Description:


This is a puzzle cache. The cache container is NOT at the posted coordinates.
You can park at the posted coordinates, and from there, you can find the true cache location on foot, but only after solving the puzzle below.
This is a SOLVE FROM ANYWHERE puzzle.


THE ACCESS

Turn down Jones Road off of Homestead Rd., heading west out of Kenora. What looks like the driveway to a Weyerhaeuser Factory is actually a road that runs far beyond the factory. You can turn onto this road @ N 49.46.756 W 094.22.207. Keep left while on this road (but not through the gates into the factory parking). It will turn to gravel, and cross a y-shaped set of tracks. Continue along the road to the listed parking coordinates: N 49.46.558 W 094.21.195



THE LESSONS

a. Tangent Ratio – (visit link)

The tangent of an angle is the ratio of the length of the opposite side to the length of the adjacent side

b. Law of Sines - (visit link)

In trigonometry, the law of sines (also known as the sine law, sine formula, or sine rule) is an equation relating the lengths of the sides of an arbitrary triangle to the sines of its angles. According to the law, where a, b, and c are the lengths of the sides of a triangle, and A, B, and C are the opposite angles
SO that: a / Sin >A = b / Sin >B = c / Sin >C




THE PUZZLE PROBLEMS

A. Tangent Ratio

Bill’s GPSr is reading that the cache he seeks is 50 ft. away, but he stands at the foot of a big cliff. Bill knows he can calculate the height of the cliff if he knows the angle to the summit. He pulls out his clinometer app on his iPod and stares at the top of the cliff. He reads an angel of 84.448 degrees. That’s a tall cliff. How tall is it?

See The Diagram

 
 
Let ‘n’ be the height of the cliff, where the true cache coordinates are N 49.46.n

NOTE: ROUND THE DECIMAL DOWN

B. Law of Sines

Bill and Bob are heading for the same cache to get the FTF, but who will get their first? (assuming they move at the same speed)
Both Bill and Bob are on the same line of longitude, but the angle between Bill and the cache is 29 degrees, while the angle between Bob and the cache is only 12 degrees. Bill is 409.44 ft away from the cache. How far is Bob from the cache?

See The Diagram

 

Let ‘w’ be how far bob is away from the cache, where the true cache coordinates are W 094.20.w

NOTE: ROUND THE DECIMAL DOWN

REMEMBER TO GET YOUR DIPLOMA!
 At each cache in the series, you will find very basic knowledge questions on a neon yelllow card. Answer the questions to obtain a set of coordinates. Solve all three puzzles and find all three caches, and you will have collected the coordiantes to the final cache, where you can pick up YOUR ‘Master Mathematician’ DIPLOMA!  The Diploma Site is: N1.N2.N3 / W1.W2.W3

GOOD LUCK!
