ok.. well its a bit complicated!!
extend 2 staright tangent lines from d and e and cross both of them!
now make a smaller traingle bt matching d and e wit a line!
then uve gt all sides 60 (an equilateral) ... ...
now work out the opp angles of qua d.. to find the required angle!

okay here you have to know some rules
(x^2)^2 will be x^2*2
and(x/2)^-1 will be (2/x)^+1 this are the rules

forgot one more (x) ^(1/2)=root of 2
here (27/x^6)^(-1/3)= (x^6/27)^(1/3)
open the bracket (x^6*(1/3))/cube root of 27
