Isabella is making a huge flag of her country, the Republic of Seychelles, on a canvas 20 by 10 meters long.

To do that, she has to draw a diagonal line that begins at the bottom-left corner and ends at the top side of the flag, 6.6 point, 6meters to the right.

Since the ends of the diagonal line are too far to put a ruler between them, Isabella wanted to find the angle of the diagonal and draw it using a protractor.

What is the angle, in degrees, between the diagonal line and the left edge of the flag?
