Hi, Here is what I see from your description.
The height of the building is b, the angles are t_{1} and t_{2} , h is the distance from the ground to your eyes and y is the difference between b and h. Knowing the angles and x you can use trigonometry to find y. Measure h and then b is h plus y. I know that this isn't following the instructions explicitly, but like you I don't see an easy way to measure the angle at your feet. Penny
