Question

The figure below shows a bamboo structure. What is the length of NB? Show all the steps you used to find your answer. (6 points)

Answer 1

remember that all lengths of a triangle can be calculated using Pythogorean Theorem\[a^2 + b^2 = c^2\]Thus solving this, we can find out the value for NC,

We also know that angle of N in Triangle ABC is 180 degrees.
All 3 triangles present are Right triangles, thus the Point N on Segment AB must be Altitude of the right triangle ABC



Using the following diagram, we can calculate e, which is the shortest side of triangle. After finding out NC (or F) we can use \[f=ab \div c\] or \[f^2 = de\] to solve the problem
