Question

Mark the statements that are true. O A. An angle that measures 180° also measures a radians. O B. An angle that measures radians also measures 45 ° 4. O C. An angle that measures radians also measures 30º. O D. An angle that measures 60° also measures radians

Answer 1

We know that

`\begin{gathered} 180^o=\pi\text{ radians} \\ 45^o=(\pi)/(4)\text{ radians} \\ 30^o=(\pi)/(6)\text{ radians} \\ 60^o=(\pi)/(3)\text{ radians} \end{gathered}`

So, options (A), (B) and (D) are true.
