Measurements were taken to find the distance between two houses. The measuring tape was only 100 feet long and the measurements had to be taken in three segments. The measurements with their 50% errors are a=(78.56ft,±0.06ft), b=(86.25ft,±0.14ft), and c=(91.48ft,±0.045ft). What is the probable error, E50, for the sum of these measurements?
