Use the sin(a - b) formula.
<span>sin(90 - x) = </span>
<span>sin90 cosx - cos90 sinx = </span>
<span>1 cosx - 0 sinx = </span>
cosx
It equals 18.32 you can go to calculatorsoup.com and it shows you
When the object lands, the height is 0
0 = -4.9t^2 + 19.6t + 58.8
0 = -4.9(t^2 - 4t - 12)
0 = (t - 6)(t + 2)
t - 6 = 0
t = 6
t + 2 = 0
t = -2....cant be this one because it is negative
ur answer is 6 seconds
