9 The value of \(\tan 10 ^ { \circ }\) is denoted by \(p\). Find, in terms of \(p\), the value of
- \(\tan 55 ^ { \circ }\),
- \(\tan 5 ^ { \circ }\),
- \(\tan \theta\), where \(\theta\) satisfies the equation \(3 \sin \left( \theta + 10 ^ { \circ } \right) = 7 \cos \left( \theta - 10 ^ { \circ } \right)\).
