WebNov 20, 2024 · Given two right triangle legs 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 WebNov 19, 2024 · This is the side-side-angle case: you know two sides a and b, and a non-included angle B. The adjacent side to angle B, a = 75.3, is larger than the opposite side, a = 51.3, so you have to compute the height, h = 75.3 sin 36.9° ≈ 45.2. The opposite side, a = 51.3, is larger than this, so there are two solutions.
WebTo solve the triangle we need to find side a and angles B and C. Use The Law of Cosines to find side a first: a 2 = b 2 + c 2 − 2bc cosA. a 2 = 5 2 + 7 2 − 2 × 5 × 7 × cos (49°) a 2 = 25 + … WebFeb 2, 2024 · Given two triangle sides and one angle If the angle is between the given sides, you can directly use the law of cosines to find the unknown third side, and then use the …
