• 13
• 17
• 23
2. Bill wants to find the width of the pond. He places stakes at A and B and then finds C so that C is a tight angle. This makes ∆ABC a right triangle. If AC = 60 feet and BC = 80 feet, about how far is it from A to B? • from 85 to 95 ft
• from 95 to 105 ft
• from 105 to 115 ft
• more than 115 ft

• 88
• 96
• Not enough information is given.

• 6 ft
• 26 ft
• 30 ft
