Use the Pythagorean Theorm for right triangles where the squares of the two legs equal the square of the hypotenuse.
Plug in the known leg and hypotenuse.
Simplify by squaring.
Isolate b by square rooting both sides.
The result is rounded
<span>B = 2S
B + 7 = 1.5(S+7)
-----
2S+7 = 1.5S + 10.5
0.5S = 3.5
