The question is in the image. Answer question 17 only.

Answer 1

Explanation

We want to convert the given problem below to degrees:

`(\pi)/(9)`

To determine the corresponding degree angle, we do this:

`multiply\text{ the angle\lparen in radians\rparen by }(180)/(\pi)`

So, we have the following:

`(\pi)/(9)*(180)/(\pi)=20\degree`

Hence, the answer is 20°.
