1.	If a cos θ − b sin θ = c, then a sin θ + b cos θ =(a) ±a2+b2+c2(b) ±a2+ b2-c2(c) ±c2-a2-b2(d) None of these
Answer» If a cos θ − b sin θ = c, then a sin θ + b cos θ = (a) $\pm \sqrt{a^{2} + b^{2} + c^{2}}$ (b) $\pm \sqrt{a^{2} + b^{2} - c^{2}}$ (c) $\pm \sqrt{c^{2} - a^{2} - b^{2}}$ (d) None of these
