    Trig Help

    If sinΘ + cosΘ=1 and sinΘ - cosΘ=1, find the number of degrees in Θ in the interval 0≤ Θ< 180.

    Thanks in advance.

    \sin{\theta} + \cos{\theta} = 1
    \sin{\theta} - \cos{\theta} = 1
    ------------------------------- add 'em up
    2\sin{\theta} = 2

    \sin{\theta} = 1

    \theta = ?
