Help please My teacher couldnt get this one

    1. The problem statement, all variables and given/known data
    I need to find the angle (theta) that when an object is launched from it, it will go the same distance vertically as horizontally. So if it went 100 feet up in the Y axis it also went 100 feet in the X axis. Thanks.
    ps. can you show me how you got this answer?

    2. Relevant equations
    ViSin(theta)(time) - 1/2at^2 = delta Y

    ViCos(theta) (2time) = delta X

    3. The attempt at a solution
    ViSin(theta)(time) - 1/2at^2 = ViCos(theta) (2time)
