i) State and prove the Pythagoras theorem.
ii) A ladder 10m long reaches a window 8m above the ground. Find the
distance of the foot of the ladder from base of the wall.​

Answer 1

Step-by-step explanation:

ii) Height of ladder =10 cm

Height of window =8 cm

The distance between foot of ladder from base of wall= X

By Pythagoras Theorem

H=P+B

10=8+X

100=64+x2

x2= 100-64

x2=36

X=6
