In the question we have given that a fence is 5 feet tall, sorry, run parallel to a tall building at a distance of 6 feet from the building.
00:40
So it will draw in case of figure the given data it will look like this.
00:46
Here we have the fence which is parallel to the tall building.
00:51
Building you will name it as y this distance is x and here we have this distance x6 now note that the ladder form a right triangle with the building and the ground so we know that the value of y square plus 6 plus x whole square is equal to c square now simplifying it we will denote this side by and here we use the pythagoras theorem.
01:44
So simplifying it we have 5 times 6 plus x is equal to, sorry, here we have by pythagoras theorem we will solve for.
01:57
Now we will solve for y.
02:03
Therefore we have 5 over x is equals to y over 6 plus x.
02:11
That simplifying you 5 times 6 plus x is equal to x times 1.
02:18
That is we have 30 plus 5 times x over x is equal to y.
02:24
Now we will take it as equation number 1...
