Which expression is always equivalent to sin x ?

• cos(90°−x)

• cos(45°−x)

• cos(2x)

• cos x

If sec 12° = cscx, find the number of degrees in the measure of acute angle x.

Select all that are true

• $\tan\left(\theta\right)=\cot\left(90-\theta\right)$

• $\csc\left(10\right)=\sec\left(80\right)$

• $\sin\left(45\right)=Cos\left(45\right)$

• $\cos\left(\theta\right)=\sin\left(\theta\right)$

Find the length of the missing side.
