Question

The result of reflecting across the line y = x and then rotating 330 degrees counterclockwise around the origin is an isometry T . Represent T by a 2 ⇥ 2 matrix. There is more than one way to do it. Use the point (1, 1) to check your answer.

I know how to make the matrices but I don't know how to combine them into one. Do I just add them?
Would you please help me?? Anyone??
no
