What happened to 15∘15^{\circ}?

Geometry Level 4

The expression (1tan⁡5+cot⁡5)(1tan⁡25+cot⁡25)(1tan⁡35+cot⁡35)(1tan⁡45+cot⁡45)\left(\dfrac{1}{\tan 5 + \cot 5}\right)\left(\dfrac{1}{\tan 25 + \cot 25}\right)\left(\dfrac{1}{\tan 35 + \cot 35}\right)\left(\dfrac{1}{\tan 45 + \cot 45}\right) can be expressed as pq\dfrac{p}{q} for positive coprime integers p,qp,q. Find p+qp+q.
