Let, the distance of the object from the top of the tower @ 45 degrees is "a". and let the distance of the object 2 from the top of tower @ 60 degrees be "b". therefore, tan45 = a/120 => a = 120
tan60 = (a+b)/120 => (3)^1/2 = (a+b)/120 => b = 87.6 m Hence, i would like to go with Option 3 as the values are very close to each other.
