    Ok, you know that in a right triangle with legs a and b, and a hypotenuse c, the following must always be true: \(\large\displaystyle c^2=a^2+b^2\) so with a hypotenuse 145 and a leg of 144 you get 145²=144²+b² 145²-144²=b²

    But " b² " is not the unknown leg (it is the unknown leg squared).

    Good for a start... You know that the unknown leg (b) is the square root of " 145²-144² " correct?

    So is the square root of " 145²-144² " equivalent to 289 or 41761

    40,000 = 200² and certainly 200 is even less than 41761. Now 145² is less than 200² and if 200² is less than 41761 then certainly 145² is less than 41761. And 145² is smaller when you subtract 144² from that, so would it make any sense if 145²-144² was equivalent to 41761 ?
