Let's do this question two, three, seven meter and four meter high stand upright on the ground.
If their bases are four meter apart, then the distance between their tops is all right.
Now, it's mentioned that the bases are four meters apart and they are now having seven meter and four
meter eight.
Right.
Let's draw the diagram.
So this is a distance between their bases, that's for meter, and this height is given a seven meter
and this height is giving us four meter, we need to find X.
All right.
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.
Let's do this constriction.
Let's draw a line parallel to the ground to this point over here that will look like this.
So this distance also will be four meters.
And over here, you're getting a distance of forming over here also.
Right.
This will be four because this total, Heidi, seven meter and because this much is four meter, we
can find that this height over here is three meters.
Now, over here.
Right, that seven minus four.
All right, now over here, we are getting a right angle triangle with sides three, four and six Asper
Pythagoras's Theorem X Square is equal to three squared plus four square.
That's nine plus 16, which is twenty five.
Therefore, X is equal to square root of twenty five, which is equal to five.
And that is your answer, which is option B.
