7. A ladder 17 m long reaches a window which is 8 m above the ground, on one side of the street. Keeping its foot at the same point, the ladder is turned to the other side of the street to reach a window at a height of 15 m. Find the width of the street.​

Answer:

by Pythagoras triplets..8,15 and 17 are triplets

hence one side of road measures 15 cm and the other measures 8 cm

hence the total width of the road is 15+8= 23

1st case

Hypotenuse (ladder)=17m

Height =8m

 base = \sqrt{17 {}^{2}  - 8 {}^{2} } \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:    \\  = \sqrt{289 - 64}  =  \sqrt{225}  = 15m

2nd case

hypotenuse (ladder)=17m

height =15m

base =  \sqrt{ {17}^{2}  -  {15}^{2} }       \\= \sqrt{289 - 225}  =  \sqrt{64}  = 8m

Adding both bases=width of the street

=15+8=23m
