    Issues using degrees in wordproblems
    I'm Missed A Few Days Of School And Now Im Lost With A Few Questions They Completed. I Have An Exam And I Hope Someone Can Help!

    1) A pendulum 25cm long is moved 30 degrees from the vertical. How much is the lower end of the pendulum raised?

    2) List 2 coterminal angles, one positive and one negative of an angle that is -190 degrees

    3) The force of attraction between 2 masses "m" and "m" varies jointly as the product of massses and inversely as the distance squared



    I Really Need Help Understanding these!

    To find the positive ones, add 360 or any multiple of 360. To find the negative ones, subtract 360 or any multiple thereof.
