If I were to do this problem, I would sketch the line 3x+4y = 5 and approximately plot the points (2,3) and (1,3). Then think...

I agree with SK. The problem is odd, in that it appears to be saying that the answer is true for any theta. So I would also look for bounds on each trig expression, to see if we know that they are no more than, or no less than, some particular value, and relate that to the graph. No really hard thinking should be needed.
