Question

please urgently solve them ​

Answer 1

Answer:

we use phythogoras theorem

${h}^{2} = {s}^{2} + {s}^{2}$

so

${15}^{2} = {12}^{2} + {x}^{2}$

so

225=144+x^2

x^2=225-144

x^2=81

$x = \sqrt{81} = 9$

there fore distance of foot of the ladder =9

hope this helps

have a nice day ahead sister
