Are you searching for the missing side or angle in a right triangle using trigonometry? Our tool is also a safe bet!Free trigonometric identity calculator - verify trigonometric identities step-by-step To arrive at this answer, we apply the Pythagorean theorem: Recall the formula a² + b² = c², where a, and b are the legs and c is the hypotenuse. In our case, a = b, so the formula reads 2a² = c². Solving for a, we get a = c/√2. Plugging in c = 10, we get the final answer: a = 10/√2 ≈ 7.07. Piotr Małek and Mateusz Mucha.If one given side is the hypotenuse of length h and the side of length p opposite to the desired angle is given, use the equation θ = sin − 1(p h). If the two legs (the sides adjacent to the right angle) are given, then use the equation θ = tan − 1(p a). Example 4.1.4: Applying the Inverse Cosine to a Right Triangle.Exercise.
