Since sinθ = 12/13 and θ is the quadrant II, it means that 90° ≤ θ ≤180° and sinθ is positive. Using trigonometric identity . cos2θ = 1 - 2sin²θ. Substituting sinθ = 12/13 into the equation, we have. cos2θ = 1 - 2sin²θ. cos2θ = 1 - 2(12/13)². cos2θ = 1 - 2(144/169) cos2θ = 1 - 288/169 personalized sports bags for kidsWebA: Solution ) sin (thetha) = -5/13 and cos (thetha) <0 Sin thetha is ( - ) and cos (thetha) <0 that….
