Answer:
x = 34
Step-by-step explanation:
ΔABD and ΔBCD are both isosceles triangles
In ΔABD
AB =AD, hence ∠ABD = ∠ADB ( base angles are equal )
∠ABD =
=
= 68°
∠DBC = 180° - 68° = 112° ( straight angle )
∠BCD = x =
=
= 34
5/6 is the correct answer!
Answer:


Step-by-step explanation:
Given (Omitted from the question)



Solving (a): 
This is calculated using:


<em>We used Total - 1 because it is a probability without replacement</em>
So, we have:





Solving (b) 
This is calculated as:








Answer:
because in the bottom eqution it shows us x-3=y therefor we could re-write the top equation as x+x-3=11
