## Algebra and Trigonometry 10th Edition

False. $csc~30°=\frac{1}{sin~30°}=\frac{1}{\frac{1}{2}}=1\frac{2}{1}=2$ $sec~30°=\frac{1}{cos~30°}=\frac{1}{\frac{\sqrt 3}{2}}=1\frac{2}{\sqrt 3}=\frac{2}{\sqrt 3}\frac{\sqrt 3}{\sqrt 3}=\frac{2\sqrt 3}{3}$
Remember $sec~30°=\frac{1}{cos~30°}$ and $csc~30°=\frac{1}{sin~30°}$, but $sin~30°\ne cos~30°$
