Question

An explanation needed too please

Answer 1

you need to use Pythagoras therum.

to help you figure it out, you can draw a 90° angled triangle.

6,8,10 Is correct because:

`6 {}^(2) + 8 {}^(2) = \\ 36 + 64 = 100 \\ \\ x {}^(2) = 100 \\ x = √(100)`

x= 10 is correct

9,12,15 is also correct. try to do what I did with 6,8,10...

16,30,34 is also correct

the wrong answer is 10,20,30

If you need anymore help tell me.
