We are asked to solve for the measurement of side BC in the given right triangle ΔABC and other side measurements were also given such as AB=1 and AC = 2. Since this is a right triangle, we can use and apply the Pythagorean theorem c²= a² + b² and the solution is shown below: c = AC b = BC a = AB AC² = AB² + BC² , substitute values we have: 2² = 1² + BC² BC² = 4-1 BC = √3 BC = 1.732
