When you have a point A and then transform it using a linear transformation (like rotation, reflections, etc.), we mark it as A' to say, "This is the point which corresponds to A after the transformations were applied". This establishes a link between the two, even though they may appear to be unrelated to someone looking at the graph.
Let θ = m∡I
tan θ = 20/21
tan⁻¹ (20/21) = θ
θ ≈ 43.60° or if you need to round to another decimal point, plug the equation I put in bold into a calculator.
