Now i tried this first by trying to find the length of the ladder before it was extended, if i have that, then i can use Pyth theorem:

AB: Using Cos 45 = [tex]\frac{4}{x}[\math]

x= 5.66m > Which i add to 0.8m = 6.46m (wrong ans)

Another way i tried finding base AB:

Tan 45 = [tex]\frac{x}{5}[\math]

x = 5m

[tex]\sqrt{5^2+5^2}[\math] = 7.07m (wrong ans)

* Right ans is 6.03m Help...?!
