The hypotenuse is √221.
To solve, use the Pythagorean theorem, a² + b² = c². The variables a and b represent the legs of the triangle, and the variable c represents the hypotenuse. Plug in the known variables of a and b, and solve for c.
a = 10
b = 11
a² + b² = c²
10² + 11² = c²
100 + 121 = c²
221 = c²
√221 = c
