WebA parallelogram has side lengths of 4 and 6 and an angle of measure 55°. Law of cosines: a2 = b2 + c2 - 2bccos (A) What is x, the length of the diagonal, to the nearest whole number? … Web$\begingroup$ To determine the ratio of the angles directly, use the law of cosines: you have the lengths of each side (equivalent to a, b, c in the formula above.) Use them to calculate the respective angle, for each angle, by using, e.g., for $\gamma$ above, that would be $$\gamma = \cos^{-1}\left(\dfrac{a^2 + b^2 - c^2}{2ab}\right)$$ $\endgroup$ – amWhy
