Question

Find the length of a ladder kept at a distance of 16 m from the foot of a wall that just reaches a window at height of 30 m.​

Answer 1

Step-by-step explanation:

Let the length of ladder=x m

Now, distance between foot of ladder and wall=5m

Height of the window from to ground=12m

∴ By using the hypotenuse theorem

∴x2=(12)2+(5)2

x=144+25

x=169

x=13

Length of the ladder is 3m
