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.
