WebSep 13, 2011 · There is a Pythagorean theorem that actually works for every triangle. Its just that for right triangles it can be simplified to A2+B2=C2 due to the properties of cosines. The law of cosines states that for a triangle with sides A, B, and C, and angles a, b, and c (with side C being opposite angle c), C2 = A2 + B2 - (2 x A x B x cos c). WebJan 13, 2024 · The hypotenuse is 11.40. You need to apply the Pythagorean theorem: Recall the formula a²+ b² = c², where a, and b are the legs and c is the hypotenuse. Put the length of the legs into the formula: 7²+ 9² = c². Squaring gives 49 + 81= c². That is, c² = 150. Taking the square root, we obtain c = 11.40.
