Hi,

I have a small math problem I am trying to figure out, and as it has been a few years since I've done much trig I'm wondering if I could get some help

I have 2 circles of radius=300m set parallel to each other that are bisecting. I know top bisection is 600m from a north side of a building to the south, and I know a 30-60-90 triangle is formed from the north front of the tower. I want to solve for all 3 distances of this triangle.

I have drawn a diagram to the best of my ability to give a more clear visual. In this diagram I want to solve for lines A, B, and H. Assume the orange line is right over the red line. I know I could form a new triangle from the circle's origin where the hypotenuse would be 300m to the bisection but I was not sure if that would form a 45-45-90 triangle to solve for length B
