How would find the value in heights and distances?
Consider this sum-->
In a right angle triangle ABC 
LACB = 27 degrees
LABC = 90 degrees
So for finding CB when AB =50m
The equation becomes-->
tan 27 = AB/BC.
so tan 27 is 0.5095
So --> BC = 50/0.5095
This calculation will take a lot of time. Is there a way to shorten it?
