Answer 1

Answer:

the share is a bit of an airplane from

Answer 2

Answer:

15.87m

Step-by-step explanation:

Length of ladder = 24m

Height = 18m

Foot of ladder from wall = x.

Using Pythagoras rule:

Hypotenuse^2 = Opposite^2 + Adjacent^2

x^2 = 24^2 - 18^2

x^2 = 576 - 324

x^2 = 252 (send the sq of x this side)

x =

$\sqrt{252}$

x = 15.87m
