  • If the length of the shadow of a tower is increasing, then the angle of elevation of the sun is also increasing.

If the length of the shadow of a tower is increasing, then the angle of elevation of the sun is also increasing.

Answer.      [False]            
Solution.     Let us take 2 cases.

 Case 1:
        
Case 2 :
             

\theta _{1} is the angle when length is small and \theta _{2} is the angle when shadow length is increased.
for finding \theta _{1}, \theta _{2} find tan \theta

\tan \theta_{1} = \frac{Perpendicular}{Base}= \frac{height\, of\, tower}{length\, of\, shadow}
\tan \theta_{2} = \frac{height\, of\, tower}{length\, of\, shadow}
In both the case height of the tower is the same but in case 2 length of the shadow is increased and if the length of shadow increased value of \theta _{2} decreased.
Hence the given statement is false.
