After the substitution z = tan (x / 2) we obtain an integrand that is a rational function of z, which can then be evaluated by partial fractions. Since the result is 2, it must mean that the opposite side divided by the djacent side equals 2. This only occurs whens the oppostie side is twice the adjacent side. Therefore it must be at an angle of 30 degrees.
