Question

From the top of a tower the angle of deppression on the car which is on the ground is 30° and the distance between the car and foot of a tower is 40m .
Then find the height of tower​

Answer 1

Answer:

Hey mate

30-40= -10 the height of the tower

Answer 2

$\huge {\red {\underline {\underline {\mathfrak {Answer}}}}}$

The height of the tower is $\frac{40}{ \sqrt{ 3} } \: m$

$\huge {\red {\underline {\underline {\mathfrak {Explanation}}}}}$

Given,

• Angle of depression = 30°
• Distance between tower and car = 40 m

Now,

$tan30° = \frac{AB}{BC} \\ = > \frac{1}{ \sqrt{3} } = \frac{AB}{40 } \\ = > 40 = AB \sqrt{3} \\ = > AB = \frac{40}{ \sqrt{3} } \: m$

•°• The height of the tower is $\frac{40}{ \sqrt{3} } \: m$
