Anja is creating a triangle using three straws. The two shorter straws have lengths of 20 cm and 21 cm. How long, in centimeters.

Let the third side, which is the hypotenuse is c .

Now we use the pythagorean identity, which is

where a and b are the legs .

Substituting the given values of the two legs, we will get

So the length of third side have to be 29 cm .
