Problems from a 15th century French manuscript, including one with negative solutions

The paperback reprint of this large collection of articles by experts on all aspects of the history and philosophy of mathematics.
This is page 167 from the Exercitationes mathematicae (1657) of Frans van Schooten (1615-1660). This book contained a collection of mathematical construction problems, among much else. It was one of the books read by Isaac Newton while he was a student at Cambridge University and helped to introduce him to modern mathematics. On this page we see a construction enabling one to find the distance across a river.
