Final answer to the problem
Step-by-step Solution
Learn how to solve equations problems step by step online. Solve the rational equation 60=arccos(10/x). Rearrange the equation. Take the inverse of \arccos\left(\frac{10}{x}\right) on both sides. Since arccos is the inverse function of cosine, the cosine of arccosine of \frac{10}{x} is equal to \frac{10}{x}. The \cos\left(60\right) equals 0.
