Question

there is a fire incident in home the fireman is trying to enter the house through wimdow as the main door is locked the window is 8m above the ground. he places a ladder against the wall such that its foot distance of 6m from the wall and its top reaches the window​

Answer 1

Let distance from ladder to window be ′X′.

Distance from ground to window = 8m

Distance from wall to firemen's foot = 6m

With pythogoras theorem :-

(8m)²+(6m)²=X²

64cm²+36cm² = X²

100cm²= X²

√100cm²= X
