Continuing with our series of videos covering all the questions from the 2018 Edexcel Higher Tier GCSE Maths Paper 2, Best Maths Tutors covers question 18, which is about 3D Trigonometry. Here we have a cuboid, and are asked to find the angle the long diagonal makes with the base. To do this we need to apply 3D trigonometry and view the shape as a series of right angled triangles.
