You don't want to plug in numbers to find it. I'll walk you through.

Remember the Pythagorean theorem for the rest of your math life. a²+b²=c²

c or your hypotenuse is ALWAYS the largest side and opposite of your 90 degree angle.

So plug in what is given.
a=20 b =? c=26

20²+b²=26² and solve for the missing variable.

400 + b² = 676
b² = 676 - 400 
b²=276

Now square each side to get rid of the ² on your variable.

You get 16.6
