1. The problem statement, all variables and given/known data You are trying to find the ideal distance that visitors should stand from the wall to view an art work. The art is 7ft high and is hung so that its bottom is 9ft from the floor. A viewer with eye level at 6 ft stands b ft from the wall. Express θ, the vertical angle subtended by the eye, as a function of b. 2. Relevant equations sinLaw?? cosLaw?? no idea 3. The attempt at a solution Code (Text): so, my main problem is that i don't understand the question !!! what is the vertical angle subtended by the eye??? Now, I drew the triangle and found that the vertical side is 10ft, the horizontal side is b ft and thats all i know! How am I supposed to find anything knowing only 1 side???
