Question

What is the value of 0 in the following image

Answer 1

We will determine the value of theta as follows:

`\begin{gathered} cos(\theta)=(10)/(21)\Rightarrow\theta=cos^(-1)((10)/(21)) \\ \\ \Rightarrow\theta\approx61.6 \end{gathered}`

So, the measurement of the angle is approximately 61.6°.
