Question
State for any acute $\angle \theta $ whether $\tan \theta $ increases or decreases as $\theta $ decreases.
  • Increases
  • Decreases
✓

Answer

For acute angles, remember what tangent means$:$ opposite over base.
If we decrease the angle, then the opposite side gets smaller.
That means $"$opposite /base$"$ decreases.
