GCSE Maths Quiz
Y = 360 - x because they make a full turn. If x = 2a then y = 360 - 2a. Then z = half of this (angles on a chord again). So z = 180 - a. So, a + z = a +(180 - a) = 180. So opposite angles add up to 180.

- It's c=2a-b. The working: In an equation with unknowns on both sides, whatever you do to one side you must do to the other. So 3c+b=2c+2a. Now get rid of 2c from both sides. So c+b=2a. Now deduct b from both sides, to get c=2a-b.
