\ a = \sqrt{c^{2} b^{2}} \ Solve for the Length of Side b The length of side b is the square root of the squared hypotenuse minus the square of side a \ b = \sqrt{c^{2} a^{2}} \ Solve for Area A of the Right Triangle The area of a right triangle is side a multiplied by side b divided by 2= a 2 ab ac ba b 2 bc ca cb c 2 Adding like terms, the final formula (worth remembering) is (a b c) 2 = a 2 b 2 c 2 2ab 2bc 2acFirst, we can expand the first equation as (a b)2 = 9 a2 2ab b2 = 9 Next, we can expand the second equation as (a −b)2 = 49 a2 −2ab b2 = 49 Then, we can add the left side of each equation and the right side of each equation giving a2 2ab b2 a2 − 2ab b2 = 9 49 a2 a2 2ab −2ab b2 b2 = 58 If A 2 B C B 2 C A C 2 A B Are In Ap Then Prove That A B C Are In Ap Mathematics Topperlearning Com Yzhqah B 25 bomber
