She now has $0 left because all together, she takes out $27 which is all she had in her account so it leaves her with $0
Answer:
degree
Step-by-step explanation:
The angle between the bottom of the ladder and the ground is given by
![cos\alpha = \frac{B}{L}](https://tex.z-dn.net/?f=cos%5Calpha%20%3D%20%5Cfrac%7BB%7D%7BL%7D)
Where
B = distance between wall of house and the foot of ladder
L = Length of the ladder
Substituting the given values we get -
![Cos \alpha = \frac{8}{25}\\Cos \alpha = 0.32\\\alpha = Cos^{-1}(0.32)\\\alpha = 71.33](https://tex.z-dn.net/?f=Cos%20%5Calpha%20%3D%20%5Cfrac%7B8%7D%7B25%7D%5C%5CCos%20%5Calpha%20%3D%200.32%5C%5C%5Calpha%20%3D%20Cos%5E%7B-1%7D%280.32%29%5C%5C%5Calpha%20%3D%2071.33)
Good afternoon.
