    Answer:

    ok is very easy

    Step-by-step explanation:

    so 1/5 of an hour is 12 mins

    and 2 is 2 hrs so that 120 mins

    now add 120+12=132

    132 x -30 degrees

    The answer to that is 132 x -30 =

    -3960 sorry if its wrong and if you get a second try put -69.1150384 rad

    I think sorry if you get it wrong have a good day
