DD is struggling with her Maths revision. Does anyone have any idea about the answer to question 5B? I have attached a photo of the question.

Any help would be fantastic Smile

Hey. If you dm me your email I can send you the answer tmrw. Can’t do it now as stuck under a sleeping child.

Which bit is she stuck on? X is just the diagonal of the base of the cube (Pythagoras).

@SonEtLumiere

Thank you for this detailed answer. Much appreciated. I have showed DD. The only thing she doesn't understand is the last bit, 180-2A. Is that the equation for a vertex angle?

Thanks for your help 😊
