Given that sinθ=5cosθ\sin \theta = 5 \cos \thetasinθ=5cosθ, find the value of tanθ\tan \thetatanθ.
Hence, or otherwise, find the values of θ \theta\,θ in the interval 0≤θ<360∘ 0 \leq \theta < 360^\circ\,0≤θ<360∘ for which
sinθ=5cosθ, \sin \theta = 5 \cos \theta, sinθ=5cosθ,giving your answers to 1 decimal place.
