A certain magnifying glass, when held 6 in. from an object, creates an image that is 10 times the size of the object being viewed. What is the measure of a 20° angle under this magnifying glass?

The angle will be still 20 degrees. The only thing that will change is the length of the sides of the angle. This however may not hold true if you are tilting the paper or the Magnifying glass. In that case you may get a curved image rather than a magnified image.
