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 that begins at the bottom-left corner and ends at the right side of the flag, at a height of 7 meters.
Since the ends of the diagonal 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 of elevation, in degrees, of the diagonal?
Round your final answer to the nearest tenth.
