Question

Fina a solution with theda in radians. 3costheda÷0.714

Answer 1

The given expression is

`3\cos \theta=0.714`

First, we divide the equation by 3

`\begin{gathered} (3\cos \theta)/(3)=(0.714)/(3) \\ \cos \theta=0.238 \end{gathered}`

Then, we find theta

`\begin{gathered} \theta=\cos ^(-1)(0.238) \\ \theta=1.33\text{rad} \end{gathered}`

Hence, the angle measures 1.33 radians.
