    1. The problem statement, all variables and given/known data
    Hi to all guys i am not good in physics and trigonometric I tried to do a projectile system.My launch point is higher than target point.I know the velocity v, target_distance d, gravity g,Launch_height_y y0.I added a image that shows the equation.I tried my own but solved the equation.Please some one help me

    d = 30,v = 22, g = 9.8 ,y0 = 2
