Question

a ladder 10m long reches a window 8m above the ground.find the foot of the ladder frome the base of the wall

Answer 1

Answer:

Given -

Length of ladder= 10m

Height of window = 8m

Distance of the floor= x

Step-by-step explanation:

Solution-

$\bold\red{Hypotenuse = height +base}$

${10}^{2} = {8}^{2} + {x}^{2} \\ \\ = 100 = 64 + {x}^{2} \\ \\ = 100 - 64 = {x}^{2} \\ \\ = {x}^{2} = 36 \\ \\ x = 6$

$so \: base \: or \: the \: distance \: between \\ the \: ladder \: and \: wall \: = {6}^{2} m = 6m$
