Answer 1

15 metreshigh above the ground the ladder will reach

Answer 2

heya!

here's ur answer frnd...

given:-

let the base be distance of ladder from the wall=8m

hypenotuse be the length of the ladder=17m

by Pythagoras thereom we will find the height.

a²+b²=c²

a²+8²=17²

a²+64=289

a²=289-64

a²=225

a=√225

a=15

hence, the height above the ground to the ladder is 15m

hope this helps...
