Let's do this question in figure ABCDE is a program, OK, so we have a program over here and a B is
equal to eight centimetre and eight is equal to six centimeter.
So we know the sounds of the program and the altitude is equal to for centimeter find the altitude corresponding
to side 80.
What would be the altitude corresponding to side 80?
You need to identify the side.
Well, what are the vertices opposite to decide either C or B right now, either from C or B, you need
to drop A perpendicular to this site to find the corresponding altitude.
Now, pause the video, give it a try, and then let's do it together.
All right.
We're back.
I hope you've given it a try.
Right now.
We need to find the altitude corresponding to site 80.
Let's mark the information given in.
The question we know is equal to eight.
Eight is equal to six and eight is equal to or.
Now, what is the area of this program area is equal to basing the height.
So if I take about as the base, that would be a B into 80.
Right.
So that's eight in four, which gives me 32 centimeters square.
All right.
Now, let me extend this side over here, OK?
And let me draw a perpendicular form pointed to B, C.
But over here, I get deep right now, we need to find the already corresponding to site 80, so that
means it's the perpendicular distance between 80 and VXI, right.
So, in fact, you can just see any point along this line and drop it perpendicular to this line.
It would give you the same height.
Even if I take this point right or this point, if I drop a perpendicular, the distance between two
parallel lines is always the same.
Right.
So if I extend it and drop it perpendicular from here to here, or if I extend BCU and rather perpendicular
from D to this side, it's one and the same for your understanding.
Let me do it like this in this case.
Right.
So I have extended back and I have dropped the perpendicular from Vertex B to the extended line over
here.
So that's deep over here.
Now we know that area is basically the height.
So if I take it as the base, the height is deep over here to area is equal to 80 into height.
Right.
Height is deep when it is the base.
Now, therefore, it goes into deep.
Also has to be equal to thirty two.
Now it's given that it is equal to six to six into deep is equal to 32 and hence deep is equal to 32.
Divided by six.
That gives you 16.
Divided by three centimeter.
And that's your answer.
