Question

the Firefighter ladder of the length 17 was kept at the at a distance of 8 metres from the building to reach the window of the building at what height the window from the ground​

Answer 1

Since the base(The ground) is perpendicular to the wall it forms a right angle and since the ladder is placed over the window it orms a triangle/Right angle triangle

By using the right hypotenuse side theoram-

a^2 + b^2 = c^2

In this condition the hypotenuse (17) and the base (8) is given

8^2 + b^2 =17^2

64 + b^2 = 289

b^2 =289 - 64

b^2=225

b=√225

b=15

Thus the height from the ground to the window is 15

Hope it helps

Answer 2

The answer is 15 units hope that helps

Explanation:

Apply pythagorean formulae here

Take the 17 as hypotenuse... And 8 as the base....

So the pythagorean formulae is

( hypotenuse) Square = (height) Square + (base) Square......

Hence put the values and the height comes as 15 units

BTW are u Indian?...
