A^2 + b^2 = c^2....where a and b are the legs, c is the hypotenuse
3^2 + b^2 = 7^2
9 + b^2 = 49
b^2 = 49 - 9
b^2 = 40.....take sqrt of both sides, eliminating the ^2
b = square root of 40 <==

Answer:
Your equation option is possibly in here somewhere.
Step-by-step explanation:
A = <em>C - 2</em>
B = A + 6 → A = <u>B - 6 </u>
<em>C - 2</em> = A = <u>B - 6</u> → B = <u><em>C + 4</em></u>
44 = C + B + A
44 = C + (<u><em>C + 4</em></u>) + (<em>C - 2</em>)
44 = 3C + 2
42 = 3C
C = 7
