1. The problem statement, all variables and given/known data A man 6ft. tall is standing x ft. from a light pole 15 ft. high. Express the length of the man's shadow L as a function of x. 2. Relevant equations Pre-Calc. NO TRIG 3. The attempt at a solution I assumed that the man's shadow creates another like triangle within in the larger one. The base of the large triangle is L + x and the height is 15 ft. The base of the small triangle is L and the height 6 ft. I set 15/(L+x) = (6/L) and solved for L. My solution was L(x)=(2/3)x, however, the book says it's L(x)=(3/2)x. Is it a typo or am I doing something wrong?
