Answer 1

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

Answer 2

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

Answer 3

I think its A or B.

Answer 4

Good for a start...

You know that the unknown leg (b) is the square root of " 145²-144² " correct?

Answer 5

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

Answer 6

you know what, lets do this....

Answer 7

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 ?

Answer 8

let me revise

Answer 9

40,000 = 200²
and certainly 200² 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 ?
