well you obviously went wrong at the end by getting the wrong answer

You should probably show your work. Then we can guide you on where you went wrong.
10 * sec(x)^2 + 5 * tan(x)^2  15 = 0
10 * (1 + tan(x)^2) + 5 * tan(x)^2  15 = 0
10 + 10 * tan(x)^2 + 5 * tan(x)^2  15 = 0
15 * tan(x)^2  5 = 0
3 * tan(x)^2  1 = 0
tan(x)^2 = 1/3
tan(x) = +/ sqrt(3)/3
So where you went wrong is that you missed 2 answers. You only gave the values from 0 to pi, rather than from 0 to 2pi.
