WebDec 20, 2016 · 1 You have a right triangle (C = 90°) with short sides a = 88 and b = 37. Solve the triangle. Always start with a sketch. From the sketch, you can see right away that this is the SAS case, or side-angle-side. To get the third side, you need the Law of Cosines, equation 31. c² = a² + b² − 2ab × cos C. c² = 37² + 88² − 2 × 37 × 88 × cos 90° WebCofunctions. Example: If sin 72° = 0.9511. find cos 18°. Show Step-by-step Solutions. Cofunction Identities in Trigonometry. The cofunction identities state that. The value of any trigonometric function at x is equal to the value of the cofunction at (π/2 - x). cos (π/2 - …
