Question

Convert the following angles measures to degrees or radius.

Answer 1

a)
`(2\pi )/(3)`

b) 330

Work:

a) To convert degrees to radians you multiply by
`(\pi )/(180)`

`(120)/(1)` x
`(\pi )/(180)`

=
`(6)/(1)` x
`(\pi )/(9)`

=
`(2\pi )/(3)`

b) To convert radians to degrees you multiply by
`(180)/(\pi )`

`(11\pi )/(6)` x
`(180)/(\pi )`

=
`(11)/(1)` x
`(30)/(1)`

= 330
