A ladder 50 cm long when set against the wall of a house just reaches a window at a
height of 48 cm. How far is the lower end of the ladder from the base of the wall?

Answer 1

Answer

so this ladder will form a right angle trianglewho's hypotenuse is 50cm and the other side is 48 cmto find third side we need to do (50)²=(48)²+(x)²,2500-2304=x²

so this ladder will form a right angle trianglewho's hypotenuse is 50cm and the other side is 48 cmto find third side we need to do (50)²=(48)²+(x)²2500-2304=x²196=x²

x²=196

x=14
