Answer:

In △ABC

tan60=BCAB

AB=3BC

Let BC=x, AB=3x

In △ABD,

tan30=BDAB

BD=AB3

BC+CD=AB3

x+40=x3(3)

x+40=3x

x=20

Thus, AB=203=34.64 cm

Answer: 34.6

Step-by-step explanation:

  • In ΔABC

           tan60^{0} = BCAB

               AB=3BC

  • Let, BC=x, AB=3x
  • InΔABD

       tan30^{0} =BDAB

                     BD=AB_{3}

            BC+CD=AB

                  x+40=3x

                          x=20

  • Thus, AB=203\\  

                        =34.64
