Isn't it that people have right not to be mistaken as communist?
Taiwan is mistakenly labeled as part of some communist country.
This is ridiculous because it's definitely not communist and has progressed toward a democratic government in last century.
It's hard to read using the format "old plain text".

The classical approach "does" provide the choice of solving the example problem algebraically and accurately.
For example, x is the length of A1B. Using the cosine law once for the triangle A1A3A2 and twice for the triangle A1A2B:
4^2=5^2+6^2-60 cos(alpha) -----(1)
d^2=5^2+x^2-10 x cos(alpha)-----(2)
x^2 = 5^2 +d ^2 -10 d cos(45 degree)-----(3)
we know cos(45 degree)=sqrt(2)/2,
from equation(1) cos(alpha)=3/4
equation (2)+(3)=>
3x=20 + 2 sqrt(2) d -----(4)
plugging equation (4) into equation (3) will give similar algebraic equation of the "rational solution"

Good point! By the way, I think standard deviation gives more sense than the variance. "Angle" does relate to the real physical world.
