    Solve for T

    This equation is killing me, Sin(2T) = (625/4) x sin(40)

    I have need to solve it for T where T is the angle. However I either end up getting an error or an angle that is less than 1 degree which i know is wrong.

    Initially i tried doing the 625/4 x sin 40 which gave me 100.44

    So i had Sin(2T) = 100.4

    then tried to take the Sin of both sides but get an error on my calculator.

    Please help me, it seems so simple to me but i just cant get my brain to work

    There must be some mistake in the original equation because after you found sin(2T) = 100.4 -----that cannot be true.
    The maximum value of the sine of any angle is only 1.00000.
