Homework Statement
In class we had a 2D with angles and components question.
Homework Equations
To find the answer I eventually got to the x=xo+vot+1/2at2 equation and came up with ***-4.9(28/37cosx)2+28tanx-3***
The Attempt at a Solution
But once I got to this point I did not know how to solve it. I would think to plug it into the quadratic formula but how can i do that if my supposed x and x2 values are not the same? One has a coefficient and cosx and the next is tanx. My teahcer plugged it into his advanced(/cheater) calculator and got x=11.9 degrees which is the right answer but i do not have that kind of calculator and do not know where to go from the equation above.
Please help!
