How to solve non right angle triangles
WebNov 20, 2024 · Use the Pythagorean theorem to calculate the hypotenuse from the right triangle sides. Take a square root of sum of squares: c = √ (a² + b²) Given an angle and one leg c = a / sin (α) = b / sin (β), explained in our law of sines calculator. Given the area and one leg As the area of a right triangle is equal to a × b / 2, then
