Question

A Status 1.4m tall,Stand on the top of a pedestal.find a point on the ground,the angle of elevation of the top of the statue is 60° and from the same point the angle of elevation of the top of the pedestal is 45° find the height of the pedestal (√3=1.732).

Answer 1

tan45=p/b

         1=x/b

         b=x------------------------1

          tan60=x+1.4/x

            √3x = x+1.4

             √3x - x =1.4

              x[√3 - 1] = 1.4

              x = 1.4/√3 - 1

                      x = 1.4/√3 - 1 *
