    Undergrad Solving systems of equations with trig functions

    Just isolate 100 cos θ in one equation, and 100 sin θ in the other equation. Square both equations. Add the two and, after using sin2+cos2=1, you are left with an equation involving cos ω Solve for ω. and return to the original to solve for θ. [I get cos ω = 92500 / 100000 = 0.925]
