An object on a platform 20m above ground level is thrown upward at an angle of 37 degrees with an initial velocity of 10m/s. Where would it land?

I think it will land 21.77m from the base of the platform.

I used the formula;
y=xtan° - (gx²)/2u²cos²°

With y= -20m (seeing that the object will land below the height of projection)
° =37°
u= 10m/s
x=? (the horizontal distance which we are looking for)


I might be wrong sha... Cuz i have that tendency so just to to find out from others.
