side a = 12m - 10m = 2m

side b = 55m

But from this web site, I get 2.08 degree launch angle

i got 30.7 degrees (3sf)...

side a = 12m - 10m = 2m

side b takes 2.5 secs to travel (time in flight). h velocity = 55/2.5

vertical V changes with time, rate of change is constant (-9.81)

for the vertical 2.0 m travelled... = (hvelocity tan x)(2.5) + (-9.81)(0.5)(2.5^2)

anddddd solve for x. 30.7.
