Answer 1

Answer:  3.7

==========================================================

Explanation:

Check out the diagram below to see what's going on.

• a = 8.2 feet
• b = unknown
• c = 9 feet

Use the pythagorean theorem to find b

$a^2 + b^2 = c^2\\\\b = \sqrt{c^2 - a^2}\\\\b = \sqrt{9^2 - (8.2)^2}\\\\b = \sqrt{81 - 67.24}\\\\b = \sqrt{13.76}\\\\b \approx 3.709 447\\\\b \approx 3.7$

The length is roughly 3.7 feet.
