A technician in a pathology laboratory is using a compound microscope to examine tissue samples. The focal length of the objective of the microscope is 0.35 cm, and the focal length of the eyepiece is 2.5 cm. The two lenses are separated by 27 cm. One day, the technician forgot to wear his contact lenses, which have a prescription of +1.5 diopters and allow him to see objects clearly at 25 cm. When he looks into the microscope without wearing his contacts, what is the approximate angular magnification of the scope?
