Question

4 A ladder 17 m long reaches a wall 15 m high. How far is the foot of the ladder from the
wall​

Answer 1

Step-by-step explanation:

hence use pythagoras formula

${ac}^{2} = {bc}^{2} + {ab}^{2}$

${17}^{2} = {bc}^{2} + {15}^{2}$

$289 = 225 + {bc}^{2}$

$289 - 225 = {bc}^{2}$

${bc}^{2} = 64$

$bc = \sqrt{64}$

BC = 8 m

hence the distance between the foot of the ladder and to the wall is 8m
