You are given the following equation:

 $\sin\left(50\right)\ =\frac{x}{12}$  
What do you need to do in order to solve for 'x'?

• Multiply both sides by 12

• Multiply both sides by 'x'

• Divide by 12 on both sides

• Have the sin(50) and 12 switch places

• Drop out of high school and become a llama trainer

Let's say you are given the following equation:

 $\cos\left(x\right)\ =\ \frac{12}{13}$  
How would you be able to solve for 'x'?

• Take the inverse cosine on both sides (a.k.a  $\cos^{-1}$  )

• Divide both sides by cosine

• Multiply both sides by cosine

• Multiply both sides by 13
