Question

A 5.5m long ladder is leaned against a wall. The ladder reaches the wall to a height of 4.4m. Find the distance between wall and foot of the ladder.

Answer 1

Answer:

We will solve this by Pythagoras Theorem

$a^2+b^2=c^2$

to apply the theory we will take the ladder length as hypotenuse and wall as perpendicular line

so $a^2$ + $(4.4)^2$ = $(5.5)^2$

= $a^2$+19.36 = 30.25

= $a^2$ = 30.25 - 19.36

= $a^2$ = 10.89

= a = $\sqrt10.89$

= a = 3.3 answer

Answer 2

Answer:

it can be considered as a right angle triangle
