Ah, so I’m assuming you have worked out BD as you said question 2, so to work out CD you could need to use the cosine rule. You have 2 sides and an angle between them (“Z” angle means that angle DBC= 56)
Because you know this, use the cosine rule to find out CD
If you’ve forgotten it:
a^2=b^2+c^2-2bcCosA

thanks I managed to calculate the answer

yesss congrats
