Answer:
The top of the ladder is now at 10 ft.
Step-by-step explanation:
At the start, we have a height H=6, a length L=10 and a base B, that has to be calculated by the Pythagorean theorem:

The base is moved twice the distance the height moves up.
We called this distance x, so we have:

The new height (H+x) is

The base travels 2x=8, so the new base B' is 0.
This means that the ladder is all against the wall (L=H').

Pedem-se várias funções trigonométricas,sabendo<span>-se que </span>senx<span> = -</span>3<span>/5 e que "x' está no seguinte intervalo: PI < x < 3PI/2 ---Veja que esse ... cosx = +-4/5 -----mas, como no 3º quadrante o </span>cosseno<span> é negativo, então temos que: ....
