not sure what "the height of A from the house" means. I suppose that you want the height of the house, since it does not change, no matter where she stands. Let that height be h.
Nor can we determine the distance of A from the house, since all w ehave are two angles. All we know is that if she walks a distance x from A to B, then x = (h-182)/(cot32° - cot40°). Since all we have are two angles, h and x can be found only in relation to each other.
