Basic trigonometry question, students are asked to find the width of a roadway in a circular tunnel given distance from edge of road to centre top of tunnel (randomised) and angle from edge of road to centre top of tunnel (randomised).

Given one or two circles centre (0,0) describe the region given by the circle inequality ( or inequalitites). e.g. x^2+y^2 < 4

Students are presented with an AI generated solution to rerrange the quadratic equation where the AI has made errors, they are asked to rewrite the solution correctly. No variables but this is version 5 of 5 versions of the question. This version uses a much more mangled AI generated solution that the other 4 versions and does not ask for the line with the first error, just for the student to rewrite the solution correctly.
