Question

5. A ladder 6m long is placed against a
vertical wall. Its lower end is 2m
away from the wall. How high on the
wall does it reach? Give your answer
to one decimal point.​

Answer 1

Answer:

5.6m

Step-by-step explanation:

It is based on the Pythagoras theorem

hypotenuse = 6m

base = 2m

length = ?

$l = \sqrt{h {}^{2} - b {}^{2} } \\ l = \sqrt{36 - 4} \\ l = \sqrt{32} \\ l = 5.65m$
