The storm

After the storm, the top of the 5 m high mast deviated by 1 m from the original vertical axis. What is the peak now? Round to 2 decimal places.

Correct answer:

x =  4.9 m

Step-by-step explanation:

$$\begin{gathered} c=5\text{m} \\ b=1\text{m} \\ {c}^2=x^2+b^2 \\ x=\sqrt{c^2-b^2}=\sqrt{5^2-1^2}=2\sqrt{6}=4.9\text{m} \end{gathered}$$
