... first need to examine the dimensions of a right triangle with those angles. Consider a right triangle, one of whose angles is 30◦ . Because the angles of a triangle add up to 180◦ , the other angle of the triangle is 60◦ . Suppose this triangle has a hypotenuse of length 1, as shown in the figure here ...
