Use the Pythagorean theorem [latex] a^{2} + b^{2} = c^{2} [/latex] to find the missing side length of a right triangle  In this case, after you plug in the given numbers your equation is [latex] 12^{2} + y^{2} = 20^{2} [/latex] Then, Just solve that equation for y. [latex]144 + y^{2} = 400[/latex] [latex] x^{2} = 256[/latex] [latex] \sqrt{} y^{2} = \sqrt{256} [/latex] y = 16 So the answer is B, 16 cm. I hope this helps, please feel free to ask questions if you're still confused :)
