(a} In the diagram, O is the centre of the circle ABCDE, = I\(\overline{BC}\)I = |\(\overline{CD}\)| and < BCD = 108°. Find < CDE. 

(b) Given that tan x = \(\sqrt{3}\), 0\(^o\) \(\geq\) x \(\geq\) 90\(^o\), evaluate 

\(\frac{(cos x)^2 - sin x}{(sin x)^2 + cos x}\)

Question number a they wrote 180 minus 107 instead of 108
and the question ask that we should find angle CDE and it is bringing ODE pls correct this

it still made the same mistake
it wrote 180 minus 107 instead of 108

because 180 minus 107 will not give you 72
