An object is launched at an angle of 60 degrees above the horizontal from the roof of a building 50 m above the horizontal ground. Find its horizontal angle if the object is launched with an initial speed of 111 m/s. Is this correct and if not can you show me what to do please?

Theta=60

V (initial)=111 m/s

LnY:

A=-9.81

V (initial)=111 * sin (60)= 96.13 m/s

V (Final)= V(initial) + a*t

0=96.13+ (-9.81*t)

T= 9.8 seconds

LnX:

D=V(initial)*t+(1/2 *0*9.8^2)

D=543.9 meters
