Question

a vertical tower of height 90 m stands on the ground. The angle of elevation of the top of the tower as observed from a point on ground is 60 degree. Find the distance of the point from the foot of the tower.

Answer 1

here is your answer.............

Answer 2

Answer;

 solution

  here,

       angle of elevation= 60

      height = 90m

      distance=?

we know,

         tan 60 = p/b

 or,           √3         = 90/b

 or,           b √3     = 90

or,            b            =  90/√3

or,           b             = 90/ 1.732 ( √3 = 1.732)

Hence, the distance is 51.96
