I met one of my Maths teacher yesterday.
We greeted and he asked me directions to the State Bank of India.
I told him make a 299 degrees turn and walk for 290 meters,
then subtend the angle of X using Pythagoras Theorem and round bit up to the nearest degree using tan ∆.
From that point, draw a parabolic curve and walk 342 meters on its major axis and bisect the straight road at an obtuse angle.
That's where the bank is.
Let him feel what I felt when I was in school....
