The cos of 20 degrees is 0.93969, the same as cos of 20 degrees in radians. To obtain 20 degrees in radian multiply 20° by π / 180° = 1/9 π. Cos 20degrees = cos (1/9 × π). Our results of cos20° have been rounded to five decimal places.

I think you may find some help here at Wikipedia.There are general trig identities and there are some surprising identities. I've linked to a section with some identities that only hold when $\alpha + \beta + \gamma = \pi = \frac{\tau}{2} = 180°$, which if you look closely might (might!) help in the denominator.. In particular, $\sin \alpha \cdot \sin \beta \cdot \sin \gamma = \frac14(\sin
