Regarding the"trig" problem.... if the intended viewer is 6 ft tall and the balcony is 6 ft out, then it this is an isosceles triangle with a right angle, thus the legs are equidistant in length. that means x=806. (I don't get to solve many problems anymore, I hope that was correct)
But I wouldn't worry about the view, as the unit will undoubtably have some windows with less obstruction. I am sure that Studio Gang have thought out the "viewing issues" for the owners, and those with balconies projecting further out will just walk out and enjoy the view as I can.
Trust me... the view from behind my 12 foot patio is outstanding, even with some building cladding on the lower 2 feet on one side of the front. I sit here and write this while watching Buckingham Fountain from my reclining lawn chair. If I want to see the wedding party in the park below, I walk up to the railing and look down.
Even my family members who are afraid of heights are getting used to it. The real gut check is cleaning the water markings off the glass lining the non-clad balcony areas. That was a trip last weekend. Got me to go out and buy a squee-gee
