Two poles of height 12 m. and 4 m. are situated in such a way that the sun rays through the top of a pole also passes through the top of other. The distance between poles is? (It is given that the sun rays make an angle of 45 degree with the horizon)

• ans: 8 m
  sol: After 4 m distance from 2nd pole(4 m) and after 12 m from 1st pole(12 m) sun light meet with ground but both meeting point is same, so dist. b/w poles =12-4=8

• For 12m pole:
  We form a right angled triangle with sun ray as hypotenuse and base and pole as sides making right angle.
  We get tan(45) = 12/base = 1
  base = 12
  
  Similarly we get base for 4m pole to be 4m.
  
  Note: the base distance is from the point where sun rays make the angle of 45 degree with horizon.
  
  So distance between poles = 12 - 4 = 8m
