Answer:
From the question we are told that
The length of the rod is
The speed is v
The angle made by the rod is
Generally the x-component of the rod's length is
Generally the length of the rod along the x-axis as seen by the observer, is mathematically defined by the theory of relativity as
=>
Generally the y-component of the rods length is mathematically represented as
Generally the length of the rod along the y-axis as seen by the observer, is also equivalent to the actual length of the rod along the y-axis i.e
Generally the resultant length of the rod as seen by the observer is mathematically represented as
=>
=>
=>
=>
=>
=>
Hence the length of the rod as measured by a stationary observer is
Generally the angle made is mathematically represented
=>
=>
