WebAug 4, 2024 · Explanation: θ can be in the first quadrant 0 ≤ θ ≤ 90 or the fourth quadrant 270 ≤ θ ≤ 360 If θ is in the first quadrant, then sinθ = 5 13 cosθ = 12 13 tanθ = 5 12 Therefore, sin2θ = 2sinθcosθ = 2 × 5 13 × 12 13 = 120 169 cos2θ = cos2θ − sin2θ = (12 13)2 − ( 5 13)2 = 144 169 − 25 169 = 119 169 If θ is in the fourth quadrant, then sinθ = − 5 13 Web1st step. All steps. Answer only. Step 1/1. Given that θ cos ( θ) = − 12 13, we know that θ is in the third quadrant (QIII) because cosine is negative in QIII. To find the remaining trigonometric functions of θ, we can use the Pythagorean theorem: ² θ ² θ sin ² θ + cos ² θ = 1. View the full answer.
