Heights and Distances:We shall now see how Trigonometry is used for finding the height and distances of various objects, without actually measuring them. Before going to problem, let us learn about to kinds of angles:The line of sight is the line drawn from the eye of an observer to the point in the object viewed by the observer.Angle of Elevation and Angle of depression:In the figure, the line AB drawn from the eye of the student top of the Minar is called the line of sight. The student is looking at the top of minar. The angle BAC, so formed by the line of sight of the horizontal, is called the angle of elevation of the top of the minar from eye of the Student.Now, consider the situation given in the beginning. The girl sitting on the balcony is looking down at a flowerpot placed on a stair of the temple. In this case, the line of sight is below the horizontal is called the angle of depression.Now, you may identify the lines of sight, and the angles so formed in the above figure are the angle of elevation or angles of depression?Problem 1:Finding the Height of Qutubminar:Let us refer to again. If you want to find the height BD of the minar without actually measuring it, what information do you need? You would need to know the following:The distance DE at which the student is standing from the foot of the minar. Let it be 28.5meters. The angle of elevation, BAC angle BAC, of the top of the minar. Let it be 450. The height AE of the student. Let it be 1.5 meters. From above coditions we can determine the height of the minar.In the figure, height of the student is CD = CB + BD.To find BC, we will use trigonometric ratios of angle A.In triangle ABC, the side BC is the opposite side in relation to known angle A.Which of the trigonometric ratios can we use? We can use the ratio has the two values that we have and the one we need to detrmine.i.e., is tanA or cotA

Very helpful videos. I love them.

[@akashroy75649]

Awesome explanation and animations are also make better understanding 👍

[@7activestudio]

Thank you so much 😀

[@shivangisingh12f68]

thank u sir ☺ it's very clear animation.the way u explain was also fluent👍

[@ranazeeshan2159]

Thanks Vinod for the video and try to speake hindi It's difgicult to understand in such a nice English I hope u can understand 🤞

[@sekmuktarali4114]

Thanks

[@log8985]

Thank u useful

[@90210dk1]

0:20 So trigonometry is just assuming the height..

[@владимирерошкин-б5р]

Your content is so touching

[@7activestudio]

Glad to hear that

[@sayedsiraj1459]

Arewah kya baat hai

[@abhisekphynix461]

Good sir

[@mallikakoner8473]

Thank you 💕💕💕💕💕

[@govideoindia]

Bouncer explanation

[@PankajKumar-ih8rt]

you can solve my problem thanks

[@AnupKumar-kn5ym]

Very nice video🙂🙂🙂

[@NINE9ESPORTS]

When you realise that Qutub Minar is not 30 metres high...But nice teaching

[@entertainment-ob9us]

How to know to put 45 digree which condition some people use 30 digree also how to know to put 45,30 or any other

[@sayedsiraj1459]

Spelling of degree is wrong

[@olinxalxo9260]

Degree spell is wrong

[@idaresitukpe1251]

What is your name

[@dynamicdeathroyals6574]

Thank you so much it helped a lot

[@7activestudio]

Glad to hear it!

[@nehavashishtha166]

Thankyou👍👍

[@anuammulu]

Nicely explained

[@7activestudio]

Thank you so much 🙂

[@devidkumar9101]

Awesome

[@khushiarora4619]

👌👌👌

[@itzme3588]

how can we know the angle in real life?, how do we measure it? im never clear how we get the angle, always "let it be"

[@DD-tr3bf]

Only reading out the from the NCERT text book

[@MohitKumar-zh1bl]

It is still helping after i years 😅

[@fabrim3406]

Thanks alot

[@motisingh5696]

It's the most easy chapter

[@littlea420]

Why do schools teach this were never gonna need this 🤬

[@rubyjha3899]

Sir isko power point me banana sikhaiye na please

[@kavithayukesh9537]

Nice

[@VivekKumar-jg7vz]

Hi, be my friend please

[@KhanBhai-uf7ty]

sir. I cant understand

[@hyeping2551]

But why not cot

[@najmatehseen737]

How u guess that BC is 28.5m... I do not understand this... If all this in guess... then what is the purpose of doing all this headache..

[@haidarniejad2168]

Wow 9 th

[@meghanavasanth1070]

If angle is 70 then how to measure

[@Drottninggatan2017]

The student is studying the minar.

[@eqlzr2]

"Therefore, in this example, if your angle of elevation is something different than 45 degrees, say 30 degrees, then this is how you proceed. And in the case of the angle of depression, this is how you proceed." Would've been a far better video if you'd taken the trouble to include those additional examples, thx.

[@90210dk1]

Fuck off and make your own video you lazy fat shit.

[@Sketcher86]

Simplified

[@Stellagang]

WAIT what if the person was a different height that means the value of the angle of elevation would be different and than you would get a different answer please explain

[@90210dk1]

This is all assumptions you assume the distance / height.. put in an angle and valour you done trig and and now you have an assumed height that no one can verify.. i,e the sun 🌝 90 million miles away never been verified WHAT A JOKE .

[@amarpreetkaur818]

Thnxxx sir

[@nagarajd2117]

[@dinudavis4230]

How to get 45 degree ???

[@prasenjitdebnath9227]

How you taken 45 degree

[@prakashkumarswain7573]

Boss the angle will be already given in the question

[@nagarajd2117]

[@sadsongs4262]

I can't understand your angreji language

[@rebelstarcreations]

🎉😂😂😂😂🎉🎉🎉🎉😢

[@averysullivan7819]

The image is too offensive

[@cansulusy9645]

thanxx sir

[@dinudavis4230]

How to get 45 degree ???

[@kr-xhian1508]

cause it's a right triangle, half 90 degrees

[@itzme3588]

@@kr-xhian1508 no there are many other possible angles too, be more specific plz
