Question

Convert each measure to degrees. Round answers to the nearest hundredth if needed.

Answer 1

\[a.) \frac{ \pi }{ 9 } b.) \frac{ -2\pi }{ 3 }\]

Answer 2

@hartnn :D

Answer 3

to convert radians into degrees,
multiply it by 180/pi
example :
pi/4 radians = pi/4 * 180/pi = 180/4 = 45 degrees.
you try both

Answer 4

note : everytime pi will get cancelled.

Answer 5

ok one sec

Answer 6

pi/9 radians = pi/9 * 180/pi = 180/9 = 20 degrees.

Answer 7

is that right?

Answer 8

absolutely correct! :D

Answer 9

omg :D k next one :D

Answer 10

-2pi/3 radians = -2pi/3 * 180/-2pi = -90/3 = -30 degrees.

Answer 11

how u got 90/3 ?
there is no -2 in the denominator, its 3

Answer 12

-2 * (180/3) =...

Answer 13

ohh its *

Answer 14

the other (easier) way to look at this will be
'just replace pi with 180'
because pi radians = 1801 degrees.

Answer 15

lol so its -120 degrees

Answer 16

** pi radians = 180 degrees.

Answer 17

can you give me the equation for b please sorry I'm just confused in the steps now

Answer 18
