Question : The angle of elevation of the top of a tower from a point on the ground is 30° and moving 70 m towards the tower it becomes 60°. The height of the tower is:

Option 1: $10$ m

Option 2: $\frac{10}{\sqrt{3}}$ m

Option 3: $10\sqrt{3}$ m

Option 4: $35\sqrt{3}$ m

Team Careers360 19th Jan, 2024

Correct Answer: $35\sqrt{3}$ m


Solution :
Let $AB$ be the tower and $C$ and $D$ be the point of observation.
$AB = h$ and CD = 70 m
In $\triangle ABD$,
$\frac{AB}{BD}=\tan$ 60°
⇒ $\frac{AB}{BD}=\sqrt3$
⇒ $BD = \frac{AB}{\sqrt3}$
⇒ $BD=\frac{h}{\sqrt3}$
In $\triangle ABC$,
$\frac{AB}{BC}= \tan$ 30°
⇒ $\frac{AB}{BC}= \frac{1}{\sqrt3}$
