Let's do this question A, it is 300 meters above the ground at a moment, it passes vertically about
another kite.
The angle of elevation of the two kites from the same point on the ground is 60 degrees and 30 degrees
in the height of the lower kite from the ground.
All right.
Pause the video, give it a try and then let's do it together.
All right, we're back.
Let's do it together.
We start withdrawing the diagram.
OK, so I have.
The two kids over here, right, let me name these points as A, B, C and D, OK, so what the guide,
which is at the greater height, is at point B and the lower grade is at point C.
OK, now it's given that B is equal to 300 meters.
Right.
And we have to find KDDI, let's CDB equal to X..
Now it's given that the angle of Elevation's are 60 degrees and 30 degrees respectively.
Right.
All right.
Now let's take the length of A.D.s white.
All right, now, what is down 60 to 90 days opposite by Addison, so Tan 60 is equal to 300 divided
by White and we know that and sixty three.
So this is equal to room three now.
Three hundred biophysical rule three.
Therefore why is equal to 300 by road trip.
OK, so this simplifies to the rule three.
OK, now let's find Diane 30.
Sudan is opposite by Addison, Sudan 30 which is this.
The angle over here is equal to X, divided by Y, and we know that Y is equal to one hundred three,
therefore ten thirty is equal to X by under three.
Now we know the value of N30 is equal to one Birute three.
Right.
So let's solve for X and we get X is equal to hundred and therefore 100 meters is the answer to this
question.
