Question

A ladder, 17.5 metres long, stands upright
against a wall. How far must the bottom of the
ladder be pulled out, so that the height of the top
may be 14 metres.​

Answer 1

Answer:

10.5

Step-by-step explanation:

by pathagorous theorem

(17.5)*2=(base)*2+(14)*2

(base)*2=(17.5)*2-(14)*2

base =√{(17.5)*2-(14)*2}

=10.5
