You are walking in a city. You are 6 feet tall and you cast a shadow that's 8 feet long. You notice that one of the buildings casts a shadow that's 160 feet long. The height of that building is feet.
Note: this is the first problem in this class to come with a Hint. Many problems in this class will have hints. Most problems will also have solutions that you can see after the set closes. (Click on "Show Solution" and once again submit an answer---but remember that this works only after the deadline for this set.) After the deadline you can also see the "answers" of a question which are the numbers (or words or choices) that WeBWorK expects you to enter.
Hint: Draw a couple of similar triangles. Assign a variable to the unknown height, write down an equation involving that variable, and solve the equation for the variable.
