Help please!

1. Measure the blind spot by closing your right eye, fixating on the X, and move your head closer or further until you can get the circle to disappear. Then do some geometry to find the visual angle of the blind spot. Measure the distance from the X to the center of the circle. Then measure the distance of the X from your left eye when the circle has disappeared. Now compute the visual angle as seen in the following diagram. Show work AB- BC AB/BC- Use the Windows calculator, found in the Accessories group of programs. Then Enter the length AB divided by BC. The units don't matter as long as you are consistent. Make sure that the degrees radio button is set. Then press Inv. Then click on tan1 to get the inverse tangent in degrees. (My example may not be the correct answer).
