Triggy Trigonometry (Posted on 2006-05-20) Difficulty: 2 of 5
A boat observes the top of a cliff to be at an angle of elevation of 25 degrees. The cliff is also at a bearing of W 30 degrees N from the boat. The boat then travels 100 meters in a straight path. The boat then observes the cliff to be due north, with an angle of elevation of 15 degrees. Using this sufficient information, calculate the height of the cliff.

I'm pretty sure that means 300 degrees, or 30 degrees north of west.
