Determine each tangent ratio using a calculator
i) $\tan 70^\circ$ $tan 7 0^{\circ}$
ii) $\tan-134^\circ$ $tan - 13 4^{\circ}$
Determine the angle to the nearest degree using a a calculator
i) $\tan \theta = 0.64$ $tan θ = 0.64$
ii) $\tan \theta = -1.45$ $tan θ = - 1.45$
Determine the angles and sides using Tangent
