WebLaw of Sines: a/sin A = b/sin B = c/sin C Put in the values we know: a/sin A = 7/sin (35°) = c/sin (105°) Ignore a/sin A (not useful to us): 7/sin (35°) = c/sin (105°) Now we use our algebra skills to rearrange and solve: Swap sides: c/sin (105°) = 7/sin (35°) Multiply both sides by sin (105°): c = ( 7 / sin (35°) ) × sin (105°) Web1 jun. 2024 · Deriving the double-angle formula for sine begins with the sum formula, sin(α + β) = sinαcosβ + cosαsinβ If we let α = β = θ, then we have sin(θ + θ) = sinθcosθ + cosθsinθ sin(2θ) = 2sinθcosθ Deriving the double-angle for cosine gives us three options.
