We know the length of two sides of the triangle and to determine the length of the hypotenuse, we just have to insert the lengths we know into the equation. c 2 = a 2 + b 2. c 2 = 9 2 + 10 2. c 2 = 81 + 100. c 2 = 181. c = 13,5 cm. We see now that the missing length of the hypotenuse is 13,5 cm and that is our result.
