Weba² = b² + c² - 2bx All you need to do now is get rid of the letter x. This is done by using basic trigonometry in the triangle AND. Since CosѲ = adjacent/hypotenuse, then x can be expressed as: x = cCosA So the final step is to substitute x = cCosA into a² = b² + c² - 2bx: a² = b² + c² - 2bcCosA (just change x to cCosA) WebNov 19, 2024 · There are four formulas that can be used to break up a product of sines or cosines.
