WebMay 19, 2024 · 1 Answer Sean May 19, 2024 tanθ = − 5 12 Explanation: . cos( − θ) = 12 13 cosθ = cos( − θ) cosθ = 12 13 sin2θ+ cos2θ = 1 sin2θ = 1 −cos2θ = 1 − 144 169 = 169 − 144 169 = 25 169 sinθ = ± 5 13 In quadrant I V, cosine is positive and sine is negative. Therefore, we will only accept the negative value of sinθ: sinθ = − 5 13 WebTrigonometry Trigonometry (from Ancient Greek τρίγωνον (trígōnon) 'triangle', and μέτρον (métron) 'measure') is a branch of mathematics concerned with relationships between … Web1.
