Answer:
x = 0.6623
y = 8
Image is attached for refernce of my solution
Step-by-step explanation:
In Δ DEF
By applying pythagoras theoram,
DE = 
=
∴ DE = 8
In Δ ABC
BC = y = 12 sin 30° = 6
AC =
+ DE + x =
+ 8 + x = 12 cos 30°
⇒ 9.73 + x = 10.39
<h3>⇒ x = 0.6623</h3>

Answer:
Sample size is 
Step-by-step explanation:
Given that,
Margin of error
%
Confidence level
%
Suppose, sample proportion
i.e. 
We know that,
Margin of error 
∴ 





squaring on both side,
∴ 
Hence, the sample size is,

Hence, the correct option is
