From the double-angle identity,
we can rewritte our given equation as:
By factoring 2cosx on the left hand side, we have
This equation has 2 solutions when
From equation (A), we obtain
and from equation (B), we have
On the other hand, we can find one more solution from the original equation by substituting x=0, that is,
then, x=0 is another solution. In summary, we have obtained the following solutions:
However, the intersection of the last set is empty. So the unique solution is x=0 as we can corroborate on the following picture:
Therefore, the solution set is: {0}
The ratio of the sides of a 30 60 90 triangle are 1 : sq root (3) : 2
So the sides are
7.4
7.4 * sq root (3) =

12.82
7.4 * 2 = 14.8
Perimeter = 7.4 + 12.82 + 14.8
