Learn The Law of Cosines with free step-by-step video explanations and practice problems by experienced tutors.In the previous section, we learned how the Law of Sines could be used to solve oblique triangles in three different situations (1) where a side and two ...The sum and difference formulas for tangent are: tan(α + β) = tanα + tanβ 1 − tanαtanβ. tan(α − β) = tanα − tanβ 1 + tanαtanβ. How to: Given two angles, find the tangent of the sum of the angles. Write the sum formula for tangent. Substitute the given angles into the formula. Simplify.Besides the two sides, you need to know one of the inner angles of the triangle. Let's say it's the angle γ = 30° between the sides 5 and 6. Then: Recall the law of cosines formula c² = a² + b² - 2ab × cos (γ) Plug in the values a = 5, b = 6, γ = 30°. We obtain c² = 25 + 36 - 2 × 5 × 6 × cos (30) ≈ 9. Therefore, c ≈ 3.Just remember that the law of cosines looks like the Pythagorean theorem. In fact, the Pythagorean theorem is the law of cosines, just a special case in which C is 90 degrees (cos90 = 0). a 2 + b 2 = c 2, but just remember to tack on the -2abcosC: a 2 + b 2 - …Michelle C.
