In simplest radical form, sec⁡(135°)\sec\left(135\degree\right)  is equal to 


 −23-\frac{\sqrt{2}}{3}  

 −2-\sqrt{2}  

 −22-\frac{\sqrt{2}}{2}  

 −32-\frac{\sqrt{3}}{2}  

Answer explanation

 sec⁡(135°)=1cos⁡(135°)=1−22\sec\left(135\degree\right)=\frac{1}{\cos\left(135\degree\right)}=\frac{1}{-\frac{\sqrt{2}}{2}}   =−22×22=−222=−2=-\frac{2}{\sqrt{2}}\times\frac{\sqrt{2}}{\sqrt{2}}=-\frac{2\sqrt{2}}{2}=-\sqrt{2}
