Question

Can someone explain how they get the answer.

Answer 1

585°

Explanation:

To convert from radians to degrees

• degree measure = radian measure ×
`(180)/(\pi )`, hence

degree measure =
`(13\pi )/(4)` ×
`(180)/(\pi )`

Cancel the π on the numerator/denominator

=
`(13(180))/(4)` = 585°

Answer 2

585°

Explanation:

2 π = 360° = 180/pi

(13pi/4) x (180/pi)

(13/4) x (180/1)

(13/1) x (45/1)

585°
