1. think about what happens when you draw a diagonal across a square, you get two triangles, use pythagoras to find the diagonal if you know that two sides of that triangle are 10

2. now its the same again, if you draw what it tells you, you get a triangle one side is 8 and one is 6, now use pythagoras

remember your trying to find the hypotenuse for each one
