WebNov 29, 2016 · Functions of 30° and 60° Now look at this diagram. I’ve drawn two 30-60-90° triangles back to back, so that the two 30° angles are next to each other. Since 2×30° = 60°, the big triangle is a 60-60-60° equilateral triangle. Each of the small triangles has hypotenuse 1, so the length 2b is also 1, which means that. b = ½ http://www.physicalgeography.net/fundamentals/6i.html WebSep 29, 2010 · The textbooks say that the maximum range for projectile motion (with no air resistance) is 45 degrees.
