Solve for θ in the equation tan θ = -4 when 0º < θ < 180º. Round your answer to the nearest tenth of a degree.
+23247 Make certain that your calculator is in degree mode.
To solve a tangent problem, use invTan or (2nd) tan
tan θ = -4 ---> θ = invTan( -4 ) ---> θ = -76.0°
But this answer isn't in your range of values.
However, tan has a period of 180°, so you can add or subtract 180° as many times as you like:
adding 180° to -76.0°, the answer becomes 104°.
I hope this helps!
