Question

A ladder is. 17m long it reaches. To a. Wiindow at a height. Above the grounnd if. Tthe foot of ladder is at a distance. 8m from. The Wall find the height of the window

Answer 1

by using Pythagoras theorem

(17)^2 = (8)^2 + height^2

height= √289-64 = √225

height of window = 15 m

hope it may help you

Answer 2

Answer:

Step-by-step explanation:

According to pythagoras theorem

(Hypotaneous)^2 = (perpendicular)^2+(base)^2

(17)^2 = ( perpendicular)^2+(8)^2

289 =(perpendicular)^2+64

(Perpendicular)^2 = 289-64

(Perpendicular)P2 = 225

Perpendicular = 15 meters

Hence height of window is 15 metres
